The purpose of this paper is to study hourly time series temperature and humidity from six meteorological stations in Oman 2009 2018. Since our data contains missing values due device failures, we have compared several methods imputation found that regression with lagging most reasonable. To extract the annual oscillations daily periodicities apply Singular Spectrum Analysis. By applying Mann–K...

Abstract This paper deals with the generalized convolutions connected Williamson transform and maximum operation. We focus on such which can define transition probabilities of renewal processes. They should be monotonic since described time or destruction does not go back, it admit existence a distribution lack memory property because analog Poisson process shall exist. Another valuable is simp...

The research was conducted to determine the extent of climate change in Sambalpur district, Odisha from year 1990 2019. studied for rainfall and temperature by running Mann-Kendall test at 5% significance level on time series data each 9 blocks period resultant statistics indicated how strong trend whether it increasing or decreasing. For seasonal six nine showed but only 3 significant trend. S...

Introduction: Different regions have various dust production; and the increase of dust storms illustrates the arid ecosystem dominance in each region. Analyzing and identifying of dust storms and its association with climatic parameters is one of the crucial approaches to reduce the caused damage of this phenomenon. Since besides determining the portion of each climate variables in intensifying...

The complexity of streamflow processes inhibits significant information about catchment performance and its sensitivity to climate change. Little is known the severity change within coastal area monsoon–subtropical zone climatic transition. This study advances a quasi-local scale analysis simplify daily dynamics their relationship with monthly hydro-climatic series (1981–2020) using six gauging...
