Why is it so hot this year?

The main reason for the excessive strengthening of subtropical storms this year is that most areas controlled by subtropical high are sunny and cloudy due to high temperature weather. Pyeongchang is just in the control area of subtropical high, so it is the cause of high temperature. Because the subtropical high in Pyeongchang is too strong, covers a large area and lasts for a long time, the sun is not blocked by clouds. Bian Xiao found out the reason why the weather is so hot this year. From the big background, in recent years, due to global warming, the frequency and intensity of extreme high temperature events in the northern hemisphere are getting higher and higher. Why is it so hot this year? The direct factor of abnormal atmospheric circulation is an important factor for the occurrence and persistence of high temperature in different regions. Specifically, from June to July this year, the western Pacific subtropical high was stronger than normal, and the early high temperature developed rapidly. In mid-July, there was less rainfall, but more precipitation. The high temperature in Europe in late June is mainly due to the clear sky radiation in the descending airflow for a long time, which is stably controlled by the high pressure ridge. Climate change has a tangible impact on every corner of the world. It is urgent to deal with global warming.
