Microphysical characteristics frontal cloud systems of different types with the presence of embedded convection according to CloudSat satellite

The aim of this work is to analyze the microphysical characteristics of the embedded convection depending on the type of front where it was formed (cold front, warm front, and occlusion front), according to CloudSat satellite.  The  following  data  were  used  for  the  research:  products  of  the  second  processing  level  "2B-GEOPROF"  and  "2B-CWC-RO"  obtained  from  CPR  radar  data  (CloudSat  satellite);  satellite  images according to the MODIS spectroradiometer. Based on the research, the following microphysical characteristics of the embedded convection of frontal cloud systems of different types (cold front, warm front, and occlusion front, respectively) according to CloudSat satellite are noted: the horizontal length of increased radar reflectivity (Z) and water content (Q) bands — 165, 170 and 230 km; heights of the foci — 4-8 km, 5-9 km and 3-6 km; the Z maximum values - 49,9, 48,8 and 50 dB; the Q maximum values  - 5,20, 1,56 and 5 g/m^3; 75th percentile radar reflectance values -6,36, -0,52, and -4,50 dB; 75th percentile values for water content 0,17, 0,21, and 0,26 g/m^3. The embedded convection cells in frontal cloud systems are characterized by the following values of the studied values: Z - from 15 to 50 dB; Q - from 200 to 1000 mg/m^3.
