Evaluating a lightning parameterization based on cloud-top height for mesoscale numerical model simulations
lightning parameterization cloud-top height mesoscale numerical model simulations
2014/12/16
The Price and Rind lightning parameterization based on cloud-top height is a commonly used method for predicting flash rate in global chemistry models. As mesoscale simulations begin to implement flas...

The rainfall and lightning activity associated with three depressions which affected the area of Cyprus were studied in order to identify possible relationships between them. The lightning data were p...
Lightning in the eastern Alps 1993-1999,part I:Thunderstorm tracks
Lightning eastern Alps 1993-1999 Thunderstorm tracks
2009/12/14
Thunderstorm tracks in the eastern Alps for the summers of 1993-1999 are investigated based on lightning data. The tracking method consists of three steps. Step one filters weak storms. Step two fixes...
Cellular automaton modelling of lightning-induced and man made forest fires
Cellular automaton modelling lightning-induced and man made forest fires
2009/12/8
The impact of forest fires on nature and civilisation is conflicting: on one hand, they play an irreplaceable role in the natural regeneration process, but on the other hand, they come within the majo...
