The results are shown below. 1） Gwadar Port has a tropical desert climate and the annual mean air temperature is 26.9 ℃. At Gwadar Port, the hottest period is from May to July and the coldest month is January. The annual and daily air temperature ranges are 12.5 ℃ and 6.5 ℃, respectively, and the air temperature difference between seasons is small. The maximum air temperature is 42.7 ℃ and the minimum is 11.9 ℃. 2） The annual mean atmospheric pressure at Gwadar Port is 1 009.1 hPa with the maximum in December and January and the minimum in July, and the seasonal differences are significant. 3） Gwadar Port is subject to subtropical high, resulting in the dry climate with little rainfall throughout the year, and the distribution of annual and seasonal precipitation is both uneven with obvious differences. The annual precipitation in 2018 is 0.3 mm, mainly in winter, while the annual precipitation in 2019 is 67.6 mm, mainly in autumn and winter. The annual mean values of relative humidity and water vapor pressure at Gwadar Port are 67.3% and 24.3 hPa. 4） Gwadar Port has an annual mean wind speed of 2.4 m·s-1, and the wind speed in the daytime is higher than that in the nighttime. In the 4 seasons, the mean wind speed is the highest in spring, followed by that in summer and autumn, and smallest is in winter. The seasonal variation of wind direction is obvious, and the prevailing wind includes southwesterly winds besides northeasterly winds. The highest frequency of wind is light breeze, followed by light air and gentle breeze, and the frequency of wind above scale 6 is zero. 查看全文 查看/发表评论 下载PDF阅读器 --> 关闭
