The rare "triple" La Nina climate may occur. What impact does it affect my country's climate?China Meteorological Administration response

According to the British "Nature" magazine recently published, meteorologists have predicted Lanna for the third consecutive year, that is, rare "triple" La Nina climatic incidents may occur.

So, what is the specific situation of the current monitoring of the La Nina phenomenon? What impact will the continuous La Nina incident have on my country? On July 5th, the China Meteorological Administration held a press conference. Xiao Yan, deputy director of the National Climate Center, responded to this. La Nina phenomenon was a manifestation of marine thermal conditions, that is, the abnormality of the sea water in the central and eastern Pacific became cold. This phenomenon affects the global climate.

Xiao Yan pointed out at the meeting that the La Nina incident is still continuing, and the decay has been slow since spring. It is expected that in the midsummer (July-August), the cold water in the Equation Middle East will be short-term attenuation, but it will still maintain a cold state of La Nina or neutral. It is expected that in the later period, cold water in autumn and winter is more likely to strengthen again.

It is reported that there have been similar phenomena for three consecutive years in history, such as 1998-2001, 1983-1986, 1973-1976.

"Unlike the impact of the El Nino incident on my country's climate in the summer of the summer, the influence of the La Nina incident is more complicated and diverse, and it is not completely related to the opposite effect of the climate of the El Nino incident." Xiao Yan said.

So, what kind of climate does the La Nina phenomenon have on my country? Xiao Yan pointed out that the following summer in most La Nina incidents, East Asian summer was strong, and the Western Pacific subtropical high -pressure was easy to north.

However, Xiao Yan also emphasized that the characteristics, center, and strength of the rainyst area in the north are very different in the summer of the different La Nina incidents. The main reason is that it will be subject to the strength of the La Nina incident. The impact of its different development trends in spring and summer will also be affected by other factors such as sea temperature, plateau snow, Arctic sea ice, and oscillation in the atmospheric season.

Among the examples of the La Nina incident in three consecutive winter, the positions of the main rainyst areas in my country in summer are also different, which once again proves the complexity of the La Nina incident on my country's summer climate. Xiao Yan also said that due to the small sample volume, the continuous Rana incident has less research on my country's climate, and more in -depth research is needed.

In terms of influence on my country's agriculture, Xiao Yan reminded that the first is to pay attention to the impact of rainstorms and floods, especially in the northern regional heavy rainstorm process on agriculture. Second, some areas of the south need to do a good job of drought response, reducing the adverse effects of continuous drought on the growth of crops.
