Please answer: spring drought, summer drought, plum rain, time, relationship. Are there any similar meteorological disasters?

Spring drought-different time in different regions.

In Guangxi, south of China, the total precipitation from February to April is less than 200mm, which is called spring drought.

Fujian Province will start 1 1- Meiyu in February.

The middle and lower reaches of the Yangtze River occur from May to early July.

In North China, it appears in March-May.

Northwest Loess Plateau, appearing in April-May.

Intermittent rain in Mao Mao (middle and lower reaches of the Yangtze River)

Meiyu (Huangmeitian) refers to the climate phenomenon of continuous rainy weather in the middle and lower reaches of the Yangtze River, Taiwan Province Province, south-central Japan, South Korea and other places every year from late June to early July. Meiyu is mainly affected by the subtropical high rising northward.

Summer drought (summer drought)

Summer drought refers to the drought in dog days, which is the hottest thirty or forty days in a year in the Central Plains. The dog days are calculated according to the lunar calendar, and the solar calendar is probably from mid-July to early August.

The time relationship between them is: spring drought → plum rain → summer drought.

Other major meteorological disasters:

Drought: In addition to spring drought and summer drought (summer drought), there is also autumn drought-from August to 10 every year, there is no soaking rain (rainfall during a continuous rainy period)

Late spring cold: refers to the weather phenomenon that the temperature rises rapidly in early spring (generally refers to March) and the temperature in late spring cold (generally refers to April or May) is lower than that in normal years.

Flood: refers to the phenomenon that low-lying areas are flooded or waterlogged due to heavy rain, heavy rain or continuous rainfall. Rain and waterlogging mainly endanger the growth of crops, resulting in crop yield reduction or crop failure, and undermining the normal development of agricultural production and other industries.

Typhoon: Typhoons (including tropical storms) generally occur between summer and autumn, with the earliest occurring in early May and the latest occurring in 1 1 month.

Lightning: It usually happens in summer.

Snow disaster: a natural disaster phenomenon that affects people's normal life because of long-term and large-scale snowfall or even snow disaster.

First frost: It will appear in autumn, winter and spring. Frost refers to the sudden drop of temperature, and the surface temperature drops below 0℃, causing damage to crops and even death.
