Thunderstorms over the Tibetan Plateau (TP), Central and Eastern China (CEC), southern foothills of Himalayas (SHF), have correlations between lightning flash rate size disagreeing with previously published negative correlation in thunderstorms different dynamics. There is a positive when comparing TP CEC thunderstorms. Compared SHF thunderstorms, much lower similar size. It explored that weake...

In order to design a tool which really suit to work situations, we have to know them. Therefore, we analyse nominal, “usual”, situations in order to know the work processes of the forecasters. Nevertheless, the SIGOONS tool will be used during critical thunderstorm phenomenon. Thus, we also analyse critical situations, that means extreme situation, emergency, crisis and disaster. Since the earl...

This paper uses thunderstorm simulations, varying properties of thunderstorms consistent with the Southeast and Northeast U.S., in an attempt to explain the differences in Hg deposition between the regions. The model analyses are useful, explained thoroughly, and well-planned. However, the paper is essentially a model parameter space exploration for soluble tracer scavenging, and the conclusion...

(1) Snow melt period of December to April in combination with precipitation (typical of lowland and hilly parts of the Labe, Vltava and Morava catchments). (2) Longer duration of rainfall lasting 10 to 72 hours (rainfall intensified and prolonged by elevation enhancement). (3) Intensive short duration of summer rainfall exceeding (flood peak occurring within hours of rainfall peak, small areas ...

Cover: A convective thunderstorm arrives near the small town of Hombori (Mali) during the AMMA field campaign (August 2005). This region is located in the Sahel, a transition zone between the Sahara and the Sudanian Savannas and stretches across the African continent. In this region, the spatial distribution of soil moisture affects the regional climate system including the spatial distribution...
