摘要

本研究使用综合分析和雨季定义来调查冈比亚1981 - 2020年的降雨模式。使用分布在冈比亚的10个气象站观测到的降雨数据。结果表明,在研究期间冈比亚有记录以来单月最高降雨量出现在该国东部地区的萨普。该站在1999年8月录得的总雨量为767毫米,而单月最低雨量是2012年9月录得的463毫米。在位于该国西部的耶尼奥伊监测站观察到了这一情况。气候学结果表明,研究区在西非季风期间经历了单峰降水,西巴诺等西段南部地区相对于研究区其他地区降水偏多。中部部分地区年降雨量最少。冈比亚东部地区从5月到10月雨水充沛,7月到9月是雨季的高峰期。在5月至10月期间,沙浦的降雨量最大,而法托的降雨量最少。研究结果还表明,7 - 9月是研究区东部地区降雨量较大的时期。虽然5月和10月都是过渡月份,但研究区东部地区10月的降雨量比5月多。另一方面,研究区的西部地区在6 - 10月获得了大量的降雨,7 - 9月是雨季的高峰期。在6月至10月期间,Sibanor的降雨量最大,而Jenoi的降雨量最少。研究结果还表明,7 - 9月是研究区西部地区降雨量较大的时期。虽然6月和10月都是过渡月份,但西部地区在6月和10月的降雨量大致相同。结果进一步发现,为避免作物需水量过剩或不足造成的损失,在东部地区,需水量高的作物应在8月前种植,因为8月降雨量最大,而需水量最小的作物应在降雨量最小的5月或10月种植。另一方面,在西部地区,需要大量水分的作物应在降雨量最大的8月或9月之前种植,而需水量最少的作物应在6月或10月种植。这项研究将有助于提高人们对气候变化导致的不稳定雨季的认识,并向农民提供冈比亚降雨分布的信息,以避免因缺水或缺水对社会、农业和环境造成的损失和影响。

Precipitation patterns in the Gambia from 1981 to 2020
The present study used composite analysis and rainy season definition to investigate rainfall patterns in The Gambia from 1981 to 2020. Rainfall dataset as observed by 10 meteorological stations scattered across The Gambia was used. Results showed that the highest single month rainfall ever recorded in The Gambia during the study period was observed in Sapu, in the eastern sector of the country. The station recorded a total rainfall amount of 767 mm in August, 1999, while the lowest single month rainfall ever recorded was 463 mm in September 2012. It was observed in Jenoi, a station situated in the western sector of the country. Climatological results showed that the study area experienced monomodal rainfall regime during the West African Monsoon, and that the southern part of the western sector region such as Sibanor tend to receive more rainfall compared to other regions of the study area. Part of the central region receives the least annual rainfall. The eastern sector of The Gambia received much of its rain from May to October with July - September as the peak of the rain season. During May - October, Sapu received the heaviest rainfall while Fatoto received the least amount. Results also show that July - September is the period when significant amounts of rainfall are received over the eastern sector of the study area. While May and October are both transitional months, the eastern sector of the study area receives more rains in October than in May. The western sector of the study area, on the other hand, received much of its rain from June to October with July - September as the peak of the rain season. During June - October, Sibanor received the heaviest rainfall while Jenoi received the least amount. The results also show that July - September is the period when significant amounts of rainfall are received over the western sector of the study area. Although June and October are both transitional months, the western sector receives more or less the same rain amounts in June and October. Results further found that, to avert losses associated with excess or deficit in crop water requirement, in the eastern sector, crops with high water requirement should be grown before August as maximum rainfall is observed in August, whereas crops with minimum water requirement should be grown in May or October, that is when minimum rainfall is experienced. In the western sector, on the other hand, crops requiring high water amount should be grown before August or September when maximum rainfall is recorded in the sector, whereas crops with minimum water requirement should be grown in June or October. This study will help create awareness on the erratic rain seasons due to Climate Change, and to provide farmers with information on rainfall distribution in The Gambia to avert losses and impacts associated with water deficit or excess on society, agriculture, and the environment.
