2018年2月15日至25日琼州海峡发生了67年不遇的持续性大雾。本文

From February 15th to 25th, 2018, the Qiongzhou Strait experienced heavy fog, which was unprecedented in 67 years. In this article, various observational data were used to diagnose and analyze the heavy fog process, and then the mesoscale WRF model was used for simulation experiments to verify the simulation results. <br>The continuous heavy fog is closely related to the continuous appearance of various types of fog. <br>Before February 22, there was more fog observed on the north coast than on the south coast, and the fog at sea lasted longer than that on land. <br>The south coast fog is more sensitive to humidity, and the north coast fog is more sensitive to wind.

From 15 to 25 February 2018, a 67-year-old continuous fog occurred in the Qiongzhou Strait. In this paper, various observations are used to make diagnostic analysis of the fog process, and then the mesoscale WRF model is used for simulation test, and the simulation results are verified.<br>This persistent fog is closely related to the emergence of several types of fog continuity.<br>Before 22 February, more fog was observed on the north shore than on the south shore, and the fog at sea lasted longer than on land.<br>The fog on the south bank is more sensitive to humidity and the fog on the north shore is more sensitive to the wind.

From February 15 to 25, 2018, a persistent heavy fog occurred in Qiongzhou Strait, which is not seen in 67 years.
