On the structure of the trade wind moist layer by Joanne Simpson ( Book )
4 editions published between 1957 and 1958 in English and held by 18 WorldCat member libraries worldwide
Comparison of the lower trade-wind air under conditions of strong versus weak circulation is continued, Moisture and thermal structure and transports from the top of the mixed layer up to the trade-wind inversion are investigated. Much less difference is found at those levels between weak and strong circulation period than was found in the lowest or mixed layer. It is shown that the development of trade cumulus convection is dependent primarily upon conditions below cloud while for immense cumulonimbus build-ups convergence in the large-scale flow appears to be necessary. A physical model of the moist layer is constructed which describes the interaction of cloud populations with their surroundings, It shows how the cloud groups, though they average level-for-level both virtually and potentially colder than the clear, are thermally direct circulations providing heat and moisture to the trade. The model is built up from numerical calculations based primarily upon the aircraft soundings made in the undisturbed trade near Puerto Rico in April 1946 and March - April, 1953

Some results of a trade cumulus cloud investigation by Joanne Simpson ( Book )
2 editions published in 1953 in English and held by 5 WorldCat member libraries worldwide
Cross sections through two trade cumulus clouds are presented, showing the temperatures, turbulence, and water vapor content of the clouds and their nearby environment, the cloud slope, and the external wind profile. The two clouds were studied over the Caribbean Sea on the same afternoon in June, 1952, and were in widely differing phases of their life cycles. The measurements were made from a slow-flying aircraft equipped with sensing instruments and whose behavior as a meteorological tool had been previously studied. Numerous calculations are made from the cross sections, including total and dynamic entrainment, drafts, slopes, and liquid water content. These are, where possible, checked against the corresponding observations. In addition to testing previously evolved theoretical models, and the usefulness of the steady-state hypothesis, the data provide some evidence concerning the formation and growth of larger trade cumulus clouds from several smaller ones and by successive stages
Concerning the structure of some cumulus clouds which penetrated the high tropical troposphere by Joanne Simpson ( Book )
2 editions published in 1954 in English and held by 5 WorldCat member libraries worldwide
Some extremely large oceanic trade-mind cumulonimbus clouds extending upwards of 40,000 ft. into a region of strong winds and intense vertical shear have been studied by means of time-lapse photography. A simultaneous still picture of the clouds taken a known distance and direction away from the motion pictures permits triangulation upon the clouds and calculation of the vertical and horizontal motions of several of the individual towers. By means of a nearby radiosonde observation, it is established that the air forming the strongest of these towers must have risen from near cloud base with little or no dilution of its buoyancy by mixing with the clear-air surroundings. The model of Malkus and Scorer (1954) concerning the erosion of cumulus towers is reviewed and tested upon these towers with satisfactory results. A minimum horizontal cloud dimension is apparently required for the production of undiluted towers. The horizontal motion of the clouds relative to the air is also estimated from the model and tested by the observations and the net upward transport of latent heat in water vapor is calculated approximately
On the formation and structure of downdrafts in cumulus clouds by Joanne Simpson ( Book )
2 editions published in 1954 in English and held by 5 WorldCat member libraries worldwide
Downdrafts, exhibiting speeds and mass transports comparable to those of the main updrafts, are a common feature of the cumulus clouds studied by the Woods Hole Oceanographic Institution's FBI aircraft in the trade-wind region. These downdrafts are observed to be most pronounced at the extreme downshear edge of the visible cloud and are generally stronger the greater the age of the cloud tower, although they are normally present at the edge of even rapidly growing turrets
On the structure of trade-wind air below cloud by Joanne Simpson ( Book )
1 edition published in 1956 in English and held by 5 WorldCat member libraries worldwide
The moisture and temperature structure of the trade-wind mixed layer are compared under conditions of strong versus weak trade. The data used are two series of aircraft psychrograph soundings made over the ocean near Puerto Rico in early spring. The first in conditions of strong undisturbed trade and high zonal index (April 10 - 28, 1946) and the second under conditions of weak rather disturbed trade and low zonal index (March 18 - April 7, 1953). The weak trade soundings show a less homogeneous moisture distribution and a less stable temperature lapse rate. Considerable variation in structure of the lowest air accompanies changes in the trade regime which may give rise to significant fluctuations in energy input at the source region for atmospheric circulations. The importance of wind stirring in the upward transfer of moisture is indicated, which may affect the formation of trade cumulus clouds. Further studies investigating the relation between air and ocean structure at their boundary are suggested by the evidence herein, which may relate to the formation of tropical storms
