Lagrangian temperature and vertical velocity fluctuations due to gravity waves in the lower stratosphere
International audience Wave-induced Lagrangian fluctuations of temperature and vertical velocity in the lower stratosphere are quantified using measurements from superpressure balloons (SPBs). Observations recorded every minute along SPB flights allow the whole gravity wave spectrum to be described...
