Abstract An accurate and complete rainfall record is prerequisite for climate studies. The purpose of this research study was to evaluate the homogeneity series Mae Klong River Basin in Thailand. Monthly data eight stations period 1971–2015 were used. double mass curve analysis used check consistency data, whereas absolute assessed using Pettitt test, standard normal Buishand von Neumann test a...

The continuous ecological management of the Loess Plateau is known throughout the world for two strategies: the integrated soil conservation project that began in the 1970s, and the “Grain for Green” project that began in the 1990s. Six sub-catchments nested in the Beiluo River basin were selected to investigate streamflow regime variations during the two project periods. The annual streamflow ...

We wish to obtain accurate structural and thermodynamic properties of both atomic and molecular fluids. Current equations used to describe such quantities have significant shortcomings. In [8], Marucho and Pettitt propose an improvement upon the existing theory. We present a computational approach to solving this new theory and enable simulations of fluid properties change as a function of flui...

Abstract The emission, transport, and deposition of desert dust are influenced by environmental factors evaluated mainly as a function precipitation, air temperature, wind. present study estimates the balance its relationship with for period 1981–2020 in Baja California Sur region, Mexico. Monthly data on wind, emission from situ measurements, reanalysis, satellite numerical parameterization sc...

Climate change is a global issue that has impact on every living being in the world. Since Malaysia is located in the tropical area where there is no distinct four seasons, analysing rainfall has therefore become one of the common assessment tools for climate change. In this study, rainfall trends and spatial variations of Langat River Basin will be determined for the period of 1971-2012. Only ...

Abstract Spatial and temporal variability of precipitation increases with the effect climate change. In this study, Seyhan Basin has been determined as study area. It is aimed to examine spatiotemporal extreme indices in Basin. For purpose, period 1970–2019 was divided into three periods change point detection methods (Pettitt, Buishand rank standard normal homogeneity test). Trends were examin...

Analysis of data can be made by replacing observations by their ranks. The analysis produces inference for the regression model where the location parameters of the observations, i, i 1⁄4 1; 2; . . . ; n, are related by 1⁄4 X . Here X is an n by p matrix of explanatory variables and is a vector of p unknown regression parameters. The observations are replaced by their ranks and an approximation...

For long periods since 1982, core inflation has behaved as if it were generated by a process with a fixed mean and serially independent error term. Nonparametric changepoint tests proposed by Pettitt (1979) and Lombard (1987) suggest that since 1982, changes in core inflation have been infrequent and rather abrupt. However, little is known about the small-sample properties, the power of the tes...

This paper revisits a widely cited study of the Boyne catchment in east Ireland that attributed greater streamflow from the mid-1970s to increased precipitation linked to a shift in the North Atlantic Oscillation. Using the method of multiple working hypotheses we explore a wider set of potential drivers of hydrological change. Rainfall– runoff models are used to reconstruct streamflow to isola...
