The Environment of Meso-scale Phenomena with Brightness Temperatures from TOVS/MSU-channel 2

This note describes the preliminary use of brightness temperatures of TOVS/MSU-channel 2 on board the satellite NOAA-11 to show the characteristic environment of meso-scale phenomena which arise alternately the convective precipitation process over the region (20o―40 o N; 90 o―110 o E) on 7―12 July 1989.The preliminary results are: (1) The brightness temperatures of the MSU-channel 2 contribute to the 700 hPa level of peak energy. It is possible to provide a certain characteristic environment of the meso-scale phenomena over the above mentioned region. (2) Cloud clusters with strong convection emerge possibly in a transition zone from the low value of brightness temperatures to the relatively high value, and rather strong precipitation appears near the high value zone
