Crachin

From Glossary of Meteorology



crachin

In the China Sea, especially in Hainan Strait and the Gulf of Tonkin north of 20°N, a period of drizzle or light rain with low stratus clouds and bad visibility that frequently occurs between late January and early April and may persist for several days.

It is associated with a fall of pressure over China and a change from a continental to a maritime air mass.
