GAME/HUBEX 1998 1999
When the area with latent instability is wide
enough, a meso-a low is able to develop from
convective systems. Latent Heat
Organization and Scale-up
5
Numerical simulation
6
When the Mei-yu front moves toward the north of
Huaihe River
The south westerly moist air in the low altitude
plays an important role for the development of
precipitation systems.

Tbb Radar Reflectivity
The convective system developed rapidly within
the observational network passed within the
dual-Doppler analysis region
9
Moist easterly in the low altitude from the ocean
plays an important role for the formation of
convergence and convective cloud systems.
