摘要

季风前阵雨发生在雨季开始之前。从3月到5月,它们会发生,可能是小毛毛雨,也可能是强雷暴。三月、四月和五月被称为季风前季节(PRMS)。PRMS记录的降水模式至关重要,因为它们对全国范围内与作物有关的广泛业务产生影响。在PRMS期间,对Kakinada地区的最高温度(TMAX)、最低温度(TMIN)、土壤湿度、相对湿度、潜热、对流有效势能(CAPE)和总可降水量(TPW)进行了分析。这些变量是使用1981年至2021年PRMS的每日ERA5再分析数据收集的。研究PRMS期间Kakinada站上空的对流相关特征是我们的目标。研究期内PRMS降水最多的5年分别是1990、1995、2008、2010和2016年,降水最少的5年分别是1990、1995、2008、2010和2016年。在季风来临前的几个月,Kakinada站的CAPE值在1000 ~ 6000 J/kg之间,TPW值在25 ~ 60 mm之间。CAPE和TPW的PRMS值均表明中强对流活动的先决条件已经满足。利用ARMA和ARIMA模型可以很好地估计PRMS期间的TPW、土壤湿度、相对湿度和CAPE参数。

Variations of Pre-monsoon season related atmospheric parameters over Kakinada region
Pre-monsoon showers occur before the beginning of the rainy season. From the months of March to May, they take place, and can be anything from little drizzles to powerful thunderstorms. March, April and May are known as the pre-monsoon season (PRMS). The precipitation patterns recorded in PRMS are critical because they have an impact on a wide range of crop-related operations across the country. During PRMS, the maximum temperature (TMAX), minimum temperature (TMIN), soil moisture, relative humidity, latent heat, convective available potential energy (CAPE), and total precipitable water (TPW) were analysed at Kakinada region. These variables were collected using daily ERA5 reanalysis data for the PRMS from 1981 to 2021. Studying the convection-related characteristics over the Kakinada station during the PRMS was our goal. During the study period, the five years with the highest PRMS rainfall were 1990, 1995, 2008, 2010 and 2016 and the five years with the lowest rainfall were 1990, 1995, 2008, 2010 and 2016. In the months leading up to the monsoon, the Kakinada station experiences CAPE values between 1000 and 6000 J/kg, while TPW values are between 25 and 60 mm. The PRMS values for CAPE and TPW both show that the prerequisites for moderate to severe convection activity have been fulfilled. TPW, soil moisture, relative humidity, and CAPE parameters during PRMS were well estimated using the ARMA and ARIMA models.
