P. Gross et A. Hense, Effects of a total solar eclipse on the mesoscale atmospheric circulation over Europe - A model experiment, METEOR ATM, 71(3-4), 1999, pp. 229-242
On August the 11th, 1999 Central Europe saw a spectacular astronomical even
t, a total solar eclipse. We present a model study concerning the meteorolo
gical effects of this eclipse in central Europe using the state-of-the-art
limited area forecast model Deutschland-Modell DM from the German Weather S
ervice DWD. Under typical summer radiation conditions very strong anomalies
in the surface energy flux and temperature in screen height are simulated.
The main temperature signal in the lower troposphere is delayed by about o
ne hour with respect to the surface. Furthermore it is connected with a wel
l defined dynamical signal which is reminiscent to a large scale land - sea
circulation. The event could be used as a test case for mesoscale atmosphe
ric models.
