The National Day balloon floated to Hokkaido, Japan. Is it really the wind?

The cyclones affecting the sea area mainly originated in Chinese mainland, and some originated in the southern part of the East China Sea, and then moved to the northeast-east direction, 1. After it is generated, part of the cyclone generated in Jiangsu and Zhejiang provinces moves northeast, passes through the Yellow Sea, passes through the central or southern part of the Korean Peninsula and enters the Sea of Japan; the other part enters the sea at the mouth of the Yangtze River, passes through the northern part of the East China Sea or the Yellow Sea, and then enters the Sea of Japan along the south bank of the Korean Peninsula. Whirlwinds that take the latter route often enter the ocean.

2. Cyclones are generated in the Yellow River Basin of China, passing through the Bohai Sea, passing through the southern end of the East Peninsula, and then passing through the central part of the Korean Peninsula into the Sea of Japan. The sea area is mainly affected by the southern part of this cyclone and the cold front;

The shortest distance from Hokkaido Zhichuang Peninsula to China is 1000 km. The Kushiro Meteorological Observatory said, "Because we don't know the type and capacity of the gas in the balloon, and we don't know when the balloon will take off, it is difficult for us to judge. However, this balloon may have been blown by the west wind at an altitude of 6000-9000 meters from the ground. " The balloon is a double-layer structure, and the outer layer is a transparent plastic ball with a diameter of 27 cm; The inner layer is a "China Red" balloon with a diameter of about 13cm. The red balloon on the inner layer is printed with a "70" pattern similar to the National Day commemorative coin, and it is also equipped with the words "Happy Birthday", "National Day" and "Celebrating the 70th Anniversary of the Founding of People's Republic of China (PRC)".

In Xia Dong, the two monsoon directions change, and the wind gradually increases. The wind direction changes from west to north to northeast. The weather is clear, the concentration is rare and the visibility is good. There was a typhoon in September. Generally, the wind force is 6-7, and it can reach more than 8 in a short time. The closer to the center, the longer the gale lasts. Due to the rainy weather, the visibility at sea is very poor. Cyclones can affect the East China Sea in the middle, especially in spring and summer. Strong cyclones with obvious development mostly appear from 165438+ 10 to April of the following year, which causes much worse weather changes than summer cyclones.

This season is the season when the wind direction changes from winter to summer monsoon, and the wind direction is chaotic, mainly southerly to the north of 35 north latitude. At 35 north latitude, there are many westerly winds and easterly winds on the Korean side, and many northerly winds on the Japanese side and the southern sea area; Cheju strait is windy from north to northwest in May.

So it is very likely that the balloon was blown away by the wind.
