How much pressure is appropriate for fishing in Yunnan?

The optimum air pressure for fishing is between 990- 1005 hectopascals.

1, the best air pressure for fishing is between 990- 1005 hectopascals, which means that high air pressure is more suitable for fishing. Generally, before the arrival of cold air, windy days and typhoons, the air pressure is relatively high, which is more suitable for fishing. Low pressure weather, bad fish mouth, not suitable for fishing. 2. In the process of fishing, you should not only learn to master the necessary skills such as time, pole and drift, but also learn to choose the right fishing position according to the change of natural environment, especially pay attention to the change of air pressure, which often depends on the final fish catch, so it is particularly important to choose a very suitable air pressure environment for fishing.

Air pressure refers to the atmospheric pressure acting on the unit area, which is numerically equal to the gravity of the vertical air column extending upward to the upper limit of the atmosphere. The international system unit is Pascal, abbreviated as Pa, and the symbol is PA. It varies not only with height, but also with temperature. The regional difference of atmospheric pressure is one of the direct causes of meteorological change and an important variable of weather forecast. Short for atmospheric pressure. Is the atmospheric pressure acting on the unit area, equal to the weight of the vertical air column extending upward to the upper limit of the atmosphere on the unit area. Air pressure is related to altitude, temperature and other conditions. It generally decreases with the increase of height. In the horizontal direction, the difference of atmospheric pressure leads to the flow of air. A unit of air pressure, usually the height of a mercury column. For example, a standard atmospheric pressure is equal to the weight of a 760mm high mercury column, which is equivalent to bearing an atmospheric pressure of 1.0336kg in an area of one square centimeter. Internationally, "hectopascals" are used as the air pressure unit. After conversion: a standard atmospheric pressure = 10 13 hectopascals (millibars). The annual average pressure in Shenzhen is 1009.8 hectopascals.
