There are two reasons for windy places: 1, there are obstacles in front and behind, forming a channel effect; There must be a large open terrain not far away.

Look at this place in Jining, which should belong to the first reason. Although it is located in the southern foothills of Phaeton Liangshan in the yinshan mountains, the wind is not stronger than that in the northern foothills. However, due to the rolling hills at the southern foot of Yinshan Mountain, the westerly winds from Hohhot and Zhuozi County will meet at the foot of Yinshan Mountain, Daqingshan Mountain and Yunmen Mountain, and turn back to the east and southeast of Urumqi, just forming a small vortex state, like a semi-closed small funnel, so there may be wind.
