Does it rain heavily in Shandong this year? Why?

Since May, 2020, many regions have released information about rainfall or typhoon this year, among which coastal cities have relatively more news. These days, everyone is discussing "Will it rain heavily in Shandong this year?" It can be said that this is indeed the most concerned issue for Shandong friends every year. Many people say that there may not be too much rain in Shandong this year, so let's take a look at a typhoon in Shandong this year. There was also a super typhoon in Shandong in 20 19, so we should pay more attention this year.

On the whole, in fact, this year's rainfall is mainly in the south, which is basically a large-scale rainfall development, which may have a certain relationship with the El Ni? o phenomenon mentioned by the National Climate Center. Everyone needs to pay more attention. But according to the next situation, this year's El Ni? o phenomenon is also short-lived and unlikely to have a long-term impact. However, under the influence of global climate change, the extreme distribution of rainfall is normal. This is probably an unnecessary science. Let's take a look at the rainfall in Shandong.

Does it rain heavily in Shandong this year?

According to the rainfall trend released by Shandong, there may not be much rainfall in May and June, because the announcement says that the "rainy season" in Shandong is expected to start in early July. And the end time is relatively early, that is, it ends in early September. Generally speaking, there are only two months of rainy season in Shandong this year. No, it can be directly seen that the rainy season this year is not very long, and compared with the rainy season all the year round, it is slightly later than normal, and there is no obvious continuous rainy weather during the wheat harvest.

Judging from the distribution of precipitation, it is estimated that the rainfall in Shandong is more in the west than in the east, with an average precipitation of 450-500mm, about 20% more precipitation, and the temperature is slightly higher than normal. Specifically, six cities of Jinan, Zibo, Dongying, Dezhou, Liaocheng and Binzhou are expected to be above 2-50%, and four cities of Qingdao, Yantai, Weihai and Rizhao are expected to be below 1-20%. The precipitation in June is expected to be 60-70 mm, less than1-20%; Estimated precipitation in July 180-2 10 mm, which is too much1-20%; The estimated rainfall in August is 180-2 10 mm, which is 20-50% more than the published data. So what we can see from the comprehensive situation is that although the rainy season is not very long and comes late, the rainfall is still not low. Most cities are mainly on the high side, and the rainfall in different months is different.

What about the typhoon?

Typhoons don't change much all year round. According to the data, there may be 1 to 2 typhoons. In 20 19, it was mainly the landing and influence of super typhoon Lichima, and other typhoons were separated from Shandong, so the impact of typhoons on Shandong was not much or great. It should be noted here that the overall typhoon in the northwest Pacific is slightly stronger this year, and it is normal for it to change in the later period. However, from our geographical position, there are not many typhoons that really affect Shandong all the year round.

Don't worry about the impact of the typhoon at all. The East China Sea does have the potential to develop typhoons, but the possibility of the Yellow Sea and Bohai Sea is extremely low and basically impossible. So this is a typhoon trend in Shandong this year. At present, after four days of development, Typhoon Wasp 1 in the northwest Pacific has basically ended, so its impact on China's marine areas has basically ended, but some areas still have the impact of airflow drive, which needs attention.

Finally, the newly generated cyclone "Ampan" in the Bay of Bengal is in the state of Grade 9. According to the data of the Central Meteorological Observatory, the storm will continue to strengthen, and it is expected to reach the level of 15 super cyclone storm on May 20, so it belongs to a super strong storm. We need to pay attention to the impact of this storm later, and the preliminary estimate is 19-22. Therefore, friends in these two provinces should observe more.

Many friends may say that this is a cyclone in the Bay of Bengal. How can it affect our country? As can be seen from the satellite cloud picture, this is a huge cyclone storm, which has just been generated, and basically all the surrounding areas have been affected, so the impact will be even greater. We are so close to the Bay of Bengal that we will be affected by the change of airflow, so this is the impact of the change of airflow.
