La Nina is expected in December to form the northern winter cold – the possibility of a large Sohu news on November 3rd afternoon, China Meteorological Bureau held a news conference. National Climate Center is studying senior engineer Zhou Bing said, at present, the central and eastern equatorial Pacific still maintain a La Nina state, is expected to become a weak La Nina event in December. According to the latest monitoring of the National Climate Center, in October (the first 29 days), the equatorial east Pacific sea surface temperature anomalies have developed over the past month, where the Nino sea temperature index of is -0.8 degrees C, SOI index was 0. At present, the central and eastern equatorial Pacific is still in a state of La nina. General 120-170 and La Nina west longitude 5 degrees north and south latitude between the equatorial Pacific sea temperature anomaly index to determine. When the SST anomaly is lower than -0.5 DEG C, is known as the "La Nina state"; if the "La Nina state" for 5 months or more, it is judged as a "La Nina event". La Nina refers to the central and eastern equatorial Pacific SST low phenomenon. Zhou Bing said, according to the monitoring standard of National Climate Center, the central and eastern equatorial Pacific in August this year to enter the state of La nina. According to the latest forecast meeting, will become a weak La Nina event in December. Zhou Bing said that La Nina phase influence in the northern hemisphere than in the southern hemisphere to some of the weak. The relationship between China’s winter weather with La Nina is obvious and generally appear after China Nina winter temperatures have the probability of more than 70% appear low temperature situation. At the same time, China is also a monsoon country, the East Asian monsoon has a very important impact on China’s winter and summer climate. In addition, China is cold in winter and not with the mid high latitude atmospheric flow and close contact with the Siberia high intensity is significantly, whether the activities of the frequent. Overall, the possibility of cold winter in northern China this year is more obvious.相关的主题文章:
