How to query real-time air pressure and fishing index

Looking at the region, the high altitude is relatively low, and the plain is generally one atmosphere.

Fishing pressure is mainly similar to human comfort, and temperature and wind direction should also be considered (this is also very important).

The so-called fishing index is actually based on the degree of influence of weather factors on fishing.

The fishing index will generally show that there are suitable, relatively suitable and unsuitable; Three indices.

Its basis is mainly to extract the main meteorological factors that affect fishing; For example, temperature, wind speed, weather phenomena, daily variation of temperature, etc. After comprehensive consideration and calculation.

Using the fishing index, people can choose suitable waters and fish under favorable meteorological conditions.

Extended data:

The fishing index is based on the influence of meteorological factors on fishing. The fishing index is divided into three grades. The higher the level, the less suitable for fishing.

Fishing index is based on the influence of meteorological factors on fishing, extracting the main meteorological factors that affect fishing: temperature, wind speed, weather phenomena, daily variation of temperature and so on. , comprehensive consideration and calculation. People can choose the right waters by fishing index.

A standard atmospheric pressure is specified as follows: the atmospheric pressure at sea level with a temperature of 0℃ and a latitude of 45 degrees is called 1 atmospheric pressure, and the value on the mercury barometer is 760 mm Hg (equivalent to10/3.25 hectopascals).

The change of atmospheric pressure is related to altitude. Atmospheric pressure is produced by gravity in the atmosphere. The higher the ground, the thinner the atmosphere, and the smaller the atmospheric pressure should be. However, because the air density related to the gravity received by the atmosphere varies unevenly with height, the atmospheric pressure decreases unevenly with height. Change with height: atmospheric pressure decreases with the increase of height.
