Southeast Asia Information Port (www.dnyxxg.com) reported on April 8th that the Hainan Provincial Meteorological Department reported continuous high temperatures in many parts of Hainan since April 4th. Among them, the highest daily temperature in Tunchang County reached 40.4℃ on April 7th, breaking the local historical record for the highest temperature in April.
The Hainan Provincial Meteorological Bureau stated that recently, the highest temperatures in many parts of Hainan have risen to 37-39℃, with some areas reaching 40℃. As of April 7th, nine cities and counties in Hainan Province have experienced temperatures above 37℃. Currently, the meteorological department has issued a level-four high-temperature warning for several consecutive days.
Is this high-temperature event an extreme event in Hainan's history? According to statistics and analysis from the Hainan Provincial Climate Center, this high-temperature process is characterized by its early onset and wide impact. On average (1991-2020), the date when the first high temperature above 37℃ occurs varies considerably across Hainan's cities and counties: it mostly occurs in April in western and northern Hainan Island, while in other areas it generally occurs between May and July.
This year, except for Chengmai, where the first instance of temperatures exceeding 37℃ occurred on the same date as usual, all other cities and counties experienced significantly earlier-than-average temperatures. Ding'an saw an earlier arrival by 42 days, and Qiongzhong by 36 days, both the second earliest since 1991; Tunchang saw an earlier arrival by 34 days, the third earliest since 1991. In terms of affected areas, this heatwave also covered a significantly larger number of cities and counties than the same period in previous years (5.2 cities and counties).
The Hainan Provincial Meteorological Department reminds the public that the current high temperatures are prolonged and feel very hot. People should take precautions against heatstroke and avoid prolonged outdoor activities and work outdoors during the hottest part of the afternoon. It is important to stay hydrated, eat a light diet, get adequate rest, and take precautions against heatstroke and other heat-related illnesses. At the same time, relevant departments should strengthen electricity and fire safety management, and ensure water resource allocation and drought relief efforts to guarantee the safety of people's lives and livelihoods.
The Hainan Provincial Meteorological Department predicts that the high temperatures will continue throughout the province in the coming days. (End)
