The difference between Jianghuai quasi-static front and Kunming quasi-static front

1, quasi-static front in Jianghuai area: The Pacific warm air mass usually moves northward between the Yangtze River and Nanling Mountains in May and June, and reaches the banks of the Yangtze River around mid-June. At this time, the cold air force controlling the Jianghuai Basin is still strong, and it is not easy to retreat northward quickly. Therefore, the cold and warm air meet in the lower reaches of the Yangtze River, resulting in a quasi-static front in the Jianghuai area and continuous rainy weather.

2. Kunming quasi-static front: mainly formed by metamorphic polar continental air mass and southwest airflow blocked by Yunnan-Guizhou Plateau topography. Clouds are low and thin, and it is easy to form continuous rainy weather.

Second, there are different regions.

1, Jianghuai quasi-static front: appears in the middle and lower reaches of the Yangtze River.

2. Kunming quasi-static front station: it appears in Yunnan-Guizhou Plateau.

Third, the characteristics are different.

1, quasi-static stop before Jianghuai: It caused the middle and lower reaches of the Yangtze River to be in a rainy state for a long time, ranging from half a month to more than two months.

2. Quasi-static front in Kunming: slow, unable to produce large-scale cloud system and precipitation, while the cold air mass under the front contains more water vapor and slides upward along the hillside. Coupled with turbulence and mixing, it is easy to form stratocumulus clouds or thick nimbostratus, often accompanied by continuous precipitation.
