Identification method of meteorological satellite cloud

From the satellite cloud images, we can see the distribution range of cloud fields in different weather systems and identify the characteristics of various clouds.

(1) Cumulonimbus cloud: Cumulonimbus cloud is easy to identify, it is a single pair of fluids, often a collection of several thunderstorm cell, and the cloud top is smooth; The scale of cumulonimbus clouds varies greatly, ranging from tens of kilometers to hundreds of kilometers, showing round and turbid clouds on satellite cloud images; The color of cumulonimbus cloud is the whitest in both visible and infrared images, and the obvious echo core can be seen in the enhanced infrared image, where the convection intensity is the largest.

(2) Cold front weather system: The cold front weather system is a very long cloud belt.

(3) Cirrus: Cirrus is a strip or large layered cloud. Because its temperature is lower than other clouds, it appears white on the infrared cloud image, which is in obvious contrast with the ground and middle and low clouds, so cirrus cloud is the clearest and easiest to identify on the infrared cloud image.

(4) Mid-cloud: Mid-cloud often appears in a large area on satellite cloud images, ranging from 200,000 to 200,000 km2, and its starting point can be vortex, ribbon, line and comma.

(5) Cumulus clouds and cumulus clouds: Cumulus clouds and cumulus clouds on satellite images are actually cumulus clouds, which often show cloud bands, cloud lines and honeycomb structures; The texture is mostly wrinkled, undulating and uneven; Stratospheric clouds and fog appear as a large smooth and uniform cloud area on the visible light cloud map, and its hue is white or gray.

(6) Turbulent clouds: Turbulent clouds are characterized by strong vortices.

Through the above characteristics, we can predict the development and movement of clouds in advance and assist the observation of meteorological elements.
