The climatology of dew points and fire weather related parameters in the Missouri-Arkansas region by Melissa D Chesser( )

1 edition published in 2010 in English and held by 2 WorldCat member libraries worldwide

Forecasting fire weather in the Springfield, Missouri and Little Rock, Arkansas Weather Forecast Offices (SGF and LZK WFO, respectively) across the greater Missouri and Arkansas regions (MoArk) county warning areas has been described as a challenge for wildfire managers. It is known that wildfire managers rely on their local WFO to provide fire weather forecast that are vital in the decision making process for wildfire suppression and prescribe fire management. Many climatic factors that affect fire hazards, including soil moisture, synoptic conditions, dewpoint, temperature and wind are indirectly impacted by ENSO. The climatology of dewpoint, temperature, Palmer Index, and synoptic conditions of fire weather flow regimes are presented here using the synoptic station observation network covering the MoArk region. A statistical analysis was performed in order to find useful interannual variability in the climatology of dew points and fire weather related parameters and their relationship to El Niño and La Niña. The data set used here contains monthly average dewpoint temperatures dating back to 1948 for three sites within Missouri: St. Louis, Columbia, and Springfield and one site in Arkansas: Little Rock. Dewpoint rather than relative humidity was chosen for this research because it is a measure of the actual amount of moisture in the air and is useful for seasonal fire weather
Climatology of atmospheric blocking 1978-2008 : global and hemispheric breakdown, as well as impacts of temperature, and global climate cycles by Shawn Patrick Riley( )

1 edition published in 2010 in English and held by 2 WorldCat member libraries worldwide

An examination of atmospheric blocking from the years 1978-2008 was conducted to explore the impacts of temperature and climate cycles on blocking intensity, blocking duration, and total blocking events on an annual basis. The data was analyzed and against global average temperature, ENSO and PDO for each year in the study in both the Northern and Southern Hemisphere. Though the course of the analyses it was found that Northern Hemispheric blocking intensity and duration were connected to the temperatures as was predicted by Lupo (1997). The annual total blocking events were found to be correlated at a significant level to the PDO. This was shown the clearest in the Southern Hemisphere, because in the Northern Hemisphere the correlation is clouded by the increase in the number of observations from the area around Siberia. The connection to the PDO, which is still a relatively new phenomena in meteorology need additional study. The connection between blocking and the PDO can have wide impacts in forecasting
Scale and stability analysis of selected atmospheric blocking events by Husain Athar( )

1 edition published in 2008 in English and held by 2 WorldCat member libraries worldwide

Global six year climatology of mid latitude atmospheric blocking events, during the period 1999-2004, is presented based on the scale and stability analysis, using the NCEP/NCAR re-analysis data. A total of 278 blocking events over the Northern as well as the Southern Hemispheres are analyzed. It is pointed out that globally, over the six year period, 83% of the blocking events have single-scale dominance, whereas remaining 17% of the blocking events have an alternating-scale dominance behavior. In the Northern Hemisphere, during the later half of the six year period, a 28% rise in the planetary-scale dominance behavior blocking events is noticed over the synoptic-scale dominance behavior blocking events. A comparison of the time variability of the three stability indicators over the entire life cycle of the selected blocking events with earlier works performing the synoptic and dynamics studies shows that the three stability indicators can be used as climatologically reliable stability indicators giving useful insight into the stability of the flow attending the blocking event. It is noticed that in the scale dependent flow, the scale that dominates during the mature stage of the blocking event determines the stability of the flow during the blocking, and that the blocking is relatively more stable state than the more frequent zonal flow, irrespective of which scale dominates the flow during blocking
Classification of air pollution regimes in the Missouri region by Eric E Weber( )

1 edition published in 2009 in English and held by 2 WorldCat member libraries worldwide

High levels of ground level ozone have been linked to large-scale weather patterns both at the surface and in the upper atmosphere. For this reason, the main focus of this study was to analyze the atmospheric conditions that are associated with high concentrations of ground level ozone in Missouri. This information can be useful for air pollution forecasting in the state of Missouri and for air pollution modeling. Knowing the conditions favorable for the formation of ground level ozone could also provide a basis for pollution control and mitigation in Missouri. The main objective was accomplished in three steps. First, an Air Quality Index for ground level ozone in Missouri was created to help locate times when high ozone concentrations took place. Next, mixing heights, transport wind speeds, and ventilation rates were analyzed to determine their contributions to these high ozone concentrations. Finally, surface and 500mb weather features were examined for each high pollution day to locate patterns at both levels. Mixing heights over Missouri were found to be fairly constant, while transport wind speeds and ventilation rates were found to be highly variable. Using just the transport wind speed offered a better indicator of high ozone days than using just the mixing height. Ventilation rate calculations were found to be highly dependent on the transport wind speed in the mixing layer. At the local level, ventilation rates were a reasonable indicator of when high ozone days would occur, while on the synoptic scale, ventilation rates were not as reliable at indicating high ozone days. At the surface, seven categories were found to be related to high ozone concentrations in Missouri, while at 500mb, four categories were found
An analysis of the spring-to-summer transition in the west central Missouri Ozarks by Rosalie Newberry( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

The spring-to-summer transition is of special importance in forecasting, as the general circulation undergoes an energy shift to a warmer regime, which affects the Midwestern United States. Beginning at the most localized scale, temperature variables are observed from surface observations at a representative station in the West Central Missouri Plains to identify the shift from late spring to early summer, with chosen guidelines for maximum temperature thresholds. Precipitation is analyzed as a summer onset validation tool, in the form of heavy precipitation event frequencies. From an upper-air analysis perspective, 500-mb height observations are examined to find a spring/summer transitional date from a chosen height minimum, as a surrogate for the jet stream, and thus a proxy for atmospheric kinetic energy. Finally, teleconnections on the planetary scale, specifically the influence of El Niño Southern Oscillation (ENSO) and Pacific Decadal Oscillation (PDO), are examined to aid in identifying the change of regime and its interannual variability. Isolating an approximate day or smaller time frame focus for the spring/summer transition will facilitate the ability to forecast seasonal pattern changes, as well as the seasonal potential for severe weather in the Missouri Plains. This, in turn, will provide safer, more economical outcomes for the population of this area
Using enstrophy-based diagnostics to examine the dynamic stability characteristics of anticyclones by Andrew David Jensen( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Blocking anticyclones are quasi-stationary atmospheric phenomena. Past research has demonstrated that blocking onset and decay periods are associated with accumulating instabilities and consequent lack of predictability. Moreover, previous results have suggested that integrated enstrophy (IRE) may be used as a measure of the instability at block onset and decay. In this dissertation, enstrophy advection (DIRE) is shown to be an indicator of instability at block onset and decay along with the IRE. More specifically, the sign of the DIRE may be used to detect the changes in instability at block onset and decay. While these enstrophy-based diagnostics are useful, a more complete understanding of them can be achieved within the framework of the two-dimensional equation of motion. Within this framework, I provide a partial answer to the question of which quantities play a role in the flow destabilization before blocking onset and decay. In particular, variations in geopotential height, relative vorticity, zonal wind, and resultant deformation tendency play a role in flow destabilization. The flow instability at block onset and decay may lead to instances in which blocking is not predicted well. Research has suggested that block decay in particular may be underpredicted. Here, the IRE and DIRE are used to evaluate the performance of the Global Ensemble Forecast System (GEFS) in predicting the onset and decay of blocking. The result is that GEFS tends to underpredict block decay. Finally, since relative maxima in the IRE have been shown to be a necessary condition for blocking onset and decay, I use the IRE here to evaluate climate model performance in simulating atmospheric blocking dynamics

This further study considers parameters relevant to most intense precipitation during another nine selected central United States events and compares them to parameters relevant to most intense precipitation during nine selected southeast, middle Atlantic and northeast United States cases. The central United States parameters found to be relevant include omega ([omega])≥‐0.20 (Pa s⁻¹) 850hpa, [omega]≥‐0.10 (Pa s⁻¹), TROWAL, CSI and EPV, Frontogenesis (850hpa, 700hpa‐500hpa), Elevated Convection, Mesoscale Gravity Wave Interaction, EPVg and CI [(800‐ 750hpa), (650‐500hpa)], Differential Vorticity Advection (850‐500hpa), mean RH≥70%(700 – 500hpa), 850hpa convergence and 250hpa divergence, enhanced IR satellite imagery, cyclonic advection of [theta]e, Q vector convergence, 1000‐500hpa critical thickness and 850hpa temperature gradients (°K). The southeast, middle Atlantic and northeast United States parameters found to be relevant include [omega]≥‐0.20 (Pa s⁻¹), Low Level Jet (LLJ), CSI/MSI and EPV, Frontogenesis (850hpa, 700hpa‐500hpa), Evaporative Cooling, Cyclone tracks and cyclogenesis, Latent Heat Release (LHR), Elevated Convection, Mesoscale Gravity Wave Interaction, EPVg and CI [(800‐ 750hpa), (650‐500hpa)], Differential Positive Vorticity Advection (700‐400hpa), TROWAL, 700hpa Absolute Vorticity, mean RH≥70%(700 – 500hpa), 850hpa convergence and 250hpa divergence, warm air advection(WAA), cold air advection(CAA), jet streak induced Ageostrophic circulation, potential vorticity(PV) advection into cyclone center, 1000‐500hpa thickness, 850hpa temperature gradients(°K) and isentropic potential vorticity(IPV). Although this study shows [omega]≥‐0.175 during all events, this research study depicts how other synoptic and mesoscale parameters interact with negative omega or each other to produce intense precipitation, in particular snowfall, during each of the studied cases, regardless of region
A study of emergency management policy regarding the use of tornado sirens during severe weather in the state of Missouri by Nicholas William Ebner( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

In recent years there have been many devastating tornadoes which have hit cities of all sizes across the state of Missouri, including St. Louis (April 22, 2011) rated EF 4, Joplin (May 22, 2011) rated EF 5 and Sedalia (May 25, 2011) rated EF-2. These, along with other catastrophic tornadoes in cities such as Tuscaloosa and Birmingham, Alabama, have increased the conversation regarding public policy of the use of tornado sirens. In many Missouri counties, guidelines and procedures regarding when to warn the public are inconsistent. After the media, emergency management directors and tornado sirens are the largest source and fastest way of informing the public of impending severe weather with the capability of producing tornadoes. With inconsistencies from county to county in Missouri and a lack of oversight by the state, uncertain and unregulated policies can cause citizens to be confused as to the specific meaning of these sirens. These variations in policy can range from who has responsibility over siren activation to the circumstances in which sirens are sounded. Frequently, in these time-sensitive situations, emergency managers do not have the sole responsibility of when to sound sirens. This decision is often left up to an assortment of individuals such as the police or fire department. It is well documented that citizens have become desensitized to tornado sirens based on the frequent number of soundings that have proven either to be a false alarm or siren activation provoked by other non-tornadic weather events. This occurs because many counties use their tornado sirens for reasons other than to alert citizens specifically of the immediate threat of tornadoes. Using a survey and archival research to gather information such as the jurisdiction policies on who activates sirens and the activation guidelines, a better understanding of how the warning process throughout Missouri was achieved. Suggestions are made that can be used by Emergency Management Directors (EMDs) when siren activation may be necessary. The goal is to use this research to assist the development of statewide guidelines on appropriate activation of tornado sirens during severe weather events. If the suggested policies are considered by EMDs, it is hopeful a unified policy throughout the state can be developed. Thus, the desensitization of the public to sirens can be reduced and allow for the effective use of tornado sirens in warning the public

A study of the connection between TV meteorologists and their viewers during severe weather broadcasts by Daniel M Ebner( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

After the devastating tornadoes in Joplin, MO and in the Deep South in 2011, it seemed appropriate to look at the impact that broadcast meteorologists (and their TV coverage) have on their viewers during severe weather events. Broadcast meteorologists play a vital role in the severe weather warning process and in persuading the public to take the appropriate actions during severe weather. This research was done by developing a survey that addressed the following questions: 1) Is the media doing everything they can persuade viewers to take shelter and protect themselves and their property?; 2) What do you do when a tornado warning is issued?; 3) Is there anything broadcast meteorologists can do or say that will make you take immediate action during severe weather? The survey was disseminated through television markets in Missouri. The goal of this research was to find new, improved and different ways of "connecting" with viewing during severe weather coverage. After looking at the results, we want to see if there are specific words, images or anything else a broadcaster can do that will trigger a response by viewers to take cover. It is my hope the results and analyses from this survey will provide broadcast meteorologists with new and improved techniques to connect with the public and to assist them in making an informed decision during severe weather events
An analysis of interannual and interdecadal variability to increase flood response preparedness of the Missouri National Guard by James M Roberts( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

River flooding and flash flooding are common occurrences in Missouri and are of special importance in forecasting. As part of the Missouri National Guard’s dual mission, it provides Defense Support to Civil Authorities and is routinely called upon to provide emergency operations to protect human life and property. Severe thunderstorms and flash flooding are possible any time of the year. River flooding is most common in the spring and summer months when the general circulation shifts to a warmer regime with water vapor more abundant. This energy shift often produces periods of frequent and heavy rain which results in flooding. An examination of flood and flash flood reports from 1949-2013 was conducted. A similar analysis was conducted on the Guard’s response to these natural disasters. Planetary scale influences of El Nino Southern Oscillation (ENSO) and Pacific Decadal Oscillation (PDO) were analyzed to identify the large-scale conditions for these phenomena. Through this analysis, a long-range predictive tool was developed to anticipate conditions significant enough to prompt a MONG State Emergency Duty in response to flooding. This forecast guidance will be used to assist emergency responders in preparing for these events, in order to save lives, property and taxpayer dollars
