The Formation of Thermals on the Ground

The measurement data from the boundary layer measurement masts in Hamburg-Billwerder (Germany) and Hyytiala (Finland) make thermals visible. For this, the temperature and humidity data must first be transformed to be independent of altitude. The subsequent visualisation of this data shows an impressive cross-section of the lower atmosphere with individual updrafts, but also with air bubbles detaching from the ground or falling from higher altitudes.

Thermals Forecast with Temps

This paper describes a simple method for estimating the strength of a thermal updraft from a Temp (i.e., a SkewT, Emagram, or similar) showing the temperature and dew point profile of the lower atmosphere. The data of the Temp can come from relevant weather models or from radiosondes.

Humidity, the Dominating Force of Thermal Updrafts

Measurements with a glider show that thermal theories published for decades need to be revised. We present a corrected view of temperature and humidity in thermal updrafts.
