What's the weather like in Dongguan these days? Is there a typhoon?

Guangdong is a subtropical region with low latitude, which is influenced by low latitude weather system. Such as subtropical high, typhoon (tropical storm), intertropical convergence zone, etc.

The western Pacific Ocean produces the most typhoons (tropical storms) every year in the world.

Guangdong is also located on the southeast coast of China. The typhoon formed in the western Pacific moved from east to west under the influence of the east-south airflow of the subtropical high, so it landed on the southeast coast of China. Therefore, many provinces along the southeast coast of China are affected by typhoons. The specific landing position of the typhoon is related to the atmospheric circulation, the specific situation of the typhoon and the season.

The mountainous terrain on land has nothing to do with the formation of typhoons, but it can weaken typhoons. The main influence of mountain topography on the weather is that precipitation will generally increase due to the topographic uplift of updraft.
