THEORETICAL INVESTIGATIONS AND MEASUREMENTS OF THERMALS

Sureyya Oney, Zafer Aslan

Abstract


The measurements of some meteorological parameters and comparison with the 1-D thermal model are presented. The meteorological parameters (temperature, relative humidity and liquid water content) and the flight data (vertical acceleration, flight altitude and speed, pressure rate) were recorded during the PUCHACZ SZD-50, SIAT and CESSNA-207 flights. The experiments were carried out in thermals, shallow cumulus clouds and within vicinity of them at Central Anatolia. In order to predict the spatial variation of parameters radiosonde data were applied for 1-D thermal model. The model results were compared with the observation results and the deviation between the two is less than l0%. In order to predict the temporal variation of meteorological parameters, some modifications are necessary in the model. This has been postponed to the next study.
