Air mass thunderstorms

air mass thunderstorms develop in a uniform warm and humid air mass,
where the temperature decreases sufficiently at altitude and
at ground level Heating mechanism due to solar radiation must take place.

The air mass thunderstorm is divided into the following types of thunderstorms.

1. Heat thunderstorms (summer thunderstorms)
   They only come about in the summer half-year.
   The air is mainly heated near the ground by the strong rays of the sun, which leads to
   evaporation of a large amount of water. Since the sun has flowed into this
   Since the cold air mass from the subsoil can already heat up considerably during the day, it ensures a
   Instability of the air layers. The warm rising air cools in the higher environment
   off, eventually condensing. Finally, in the moisture-labile atmosphere,
   triggered thermal thunderstorms. These usually occur in the afternoon or evening.

2. winter thunderstorm
   Winter thunderstorms often occur in the winter months and have a similar history
   like heat storms. In contrast to warm thunderstorms, there is usually no sufficient
   strong solar radiation, which is why a high temperature gradient can only be achieved by strong cooling
   can occur in the upper layers. This is achieved with the supply of cold air from the altitude into the
   Paths led, which often has a polar origin. Over the lake, the vertical current
   of the air masses thermally by the strong temperature gradient within the fairly
   warm sea surface and the rather cold air layered over it.
   Winter weather is most common between midday and afternoon. The one in the lower
   Layered heated air is sufficiently unstable to trigger convection.
   The weather phenomena are most extreme in the coastal areas.
   Winter thunderstorms are characterized by heavy lump showers and snow showers. This
   In contrast to thermal thunderstorms, thunderstorms are less extreme because the colder air is less
   contains water vapor and thus has less energy.

Airmass thunderstorms occur in a uniform airmass, i. H. the temperature changed
hardly move in the horizontal direction. However, the temperature must increase sufficiently with height
decrease and there must be a heating mechanism close to the ground (thermal release).
