How to inquire about global typhoon weather

Meteorological satellites are divided into solar orbit meteorological satellites and geostationary orbit meteorological satellites according to their orbits. The meteorological satellite tracking typhoon is a geostationary orbit meteorological satellite, which belongs to fixed-point photography. Just take pictures of the typhoon moving.

Spaceborne meteorological remote sensors receive and measure visible light, infrared and microwave radiation from the earth and its atmosphere, as well as electromagnetic waves reflected by satellite navigation systems. It is converted into an electrical signal and transmitted to the ground station. The ground station recovers the electric signal sent by the satellite and maps it to various clouds, wind speeds and directions. After further processing and calculation, the sea surface and charts get various meteorological data.

Structure of typhoon:

Typhoon Eye Area: It's strange that the wind here is very light and the weather is sunny, with an average diameter of 40 kilometers. The sailors who participated in it humorously called Typhoon Eye "Xanadu".

Cloud wall area: the cloud wall area with a width of tens of kilometers and a height of more than ten kilometers around the typhoon eye, also called eye wall. The cloud wall is towering here, the wind is howling, the rain is pouring, the sea is churning, and the weather is the worst.

Spiral rain belt area: Outside the cloud wall, there are spiral rain belts, and several rain (cloud) belts gather spirally around the eye wall. The rain is tens to hundreds of kilometers wide and several Qian Qian meters long. There will be showers and windy weather where the rain belt passes.
