ABSTRACT: Analysis
of the cloud macro characteristics of typhoon “Mekkhala” is based on FY-4A stationary
meteorological satellite data. Aiming at the precipitation process during the
“Mekkhala” tropical storm and typhoon, the precipitation structure
characteristics were analyzed using the precipitation data retrieved from polar
orbiting satellites. The results show that: in the life process of “Mekkhala”,
its cloud system always presents an asymmetric structure, and the cloud area
and cloud top height on the north and south sides also change constantly. When the intensity of “Mekkhala”
reaches the maximum, its minimum brightness temperature range is also
the largest, and the spiral structure is also the most obvious; during the
precipitation process of the “Mekkhala” tropical storm and typhoon, the near-surface precipitation
rate is roughly distributed in a ring shape, from the precipitation rate of the
FY3-D polar-orbiting satellite and the GCOM-W1 satellite. In terms of product
comparison, the precipitation rate product of the GCOM-W1 satellite responds
better to low-level precipitation.
