Mobile high pressure
Mobility high pressures are high pressures that move at high speeds between low pressures, unlike cold high and warm pressures, which run for a long time at stagnant or very slow speeds. The migratory high pressure corresponds to the shortwave ridge of the westerly waves. In the autumn and winter, the southeastern part of the Siberian high pressure falls off and the mobile high pressure passes around the Korean peninsula. It was originally a cold high pressure, but it shifted to warm atmospheric pressure in a few days when it moved southeast on warm seacoast. The speed of the mobile high pressure passing around the Korean Peninsula is about 45km per hour, which is fast in the cold season and slow in the warm season. Mobility high pressure is generally cloudy and weather is good, but it is cloudy because it is not strong enough for high pressure.
