Recently Møller, Pettitt, Berthelsen and Reeves [17] introduced a new MCMC methodology for drawing samples from a posterior distribution when the likelihood function is only specified up to a normalising constant. We illustrate the method in the setting of Bayesian inference for Markov point processes; more specifically we consider a likelihood function given by a Strauss point process with pri...

Abstract This study investigates rainfall and drought characteristics in southeastern Australia (New South Wales Victoria) using data from 45 stations. Four homogeneity tests are adopted to determine inhomogeneities the annual total (ATR) monthly data, namely The Pettitt test, SNHT, Buishand range test Von Neumann ratio at significance levels of 1%, 5%, 10%. Temporal trends (ATR, monthly, seaso...

Satellite-based precipitation products can be a better alternative of rain gauges for hydro-meteorological studies in data-poor regions. This study aimed to evaluate how regional and seasonal drought patterns had changed the Ganga–Brahmaputra Basin between 1983 2020 with PERSIANN-CDR data. The spatial pattern winter drought, monsoon Standardized Precipitation Index (SPI) calculated different ti...

Recently it has been suggested that one or more large extraterrestrial (ET) objects struck northern North America 12,900 +/- 100 calendar years before present (calBP) [Firestone RB, et al. (2007) Proc Natl Acad Sci USA 104: 16016-16021]. This impact is claimed to have triggered the Younger Dryas major cooling event and resulted in the extinction of the North American megafauna. The impact is al...

The analysis of precipitation, snow cover, and temperature based on measured data is important for many applications in hydrology, meteorology, climatology, disaster management, human activities. In this study, we used long-term historical datasets from the Varzob River Basin (VRB) Tajikistan to evaluate trend magnitudinal changes temperature, cover area Anzob (upstream), Maykhura (midstream), ...

In recent years, numerous studies have been carried out on changes in the temperature and precipitation regimes frequency of extreme events that are a result climate change. While there is evidence an increase at global level, this globality does not seem to occur with precipitation. The Igeldo weather station (San Sebastian) has one longest recorded rainfall intensity series Spain can be consi...

Abstract Despite the increased frequency of extreme climate events including their significance in Nepal's socio-economy, studies have seldom considered extremes, and even fewer them combination with temperature precipitation. This study aimed at examining trend variables Gandaki Province, Nepal. Daily precipitation data five stations between 1990 2020 were analyzed. Modified Mann–Kendall Sen's...

Le changement climatique et l’anthropisation sont les principaux forçages qui influencent significativement la variabilité des écoulements cours d’eau. Cependant, compréhension de leur impact simultané sur reste limitée. L’objectif cette étude est d’appréhender l’impact précipitations du bassin versant Mefou une période récente (1950-51 à 2018-2019). Pour cela, données hydropluviométriques conc...

In recent years, climatic changes have had a greater impact on the hydrological cycle, leading to continuous in climate both temporal and spatial scales. Therefore, this study aimed verify credibility homogeneity of data, so when conducting any field change, data used must be tested. current study, eight stations distributed Nineveh Governorate were selected, using represented by (rainfall, max...

Since the beginning of 21st century, net primary productivity (NPP) grassland in Three-Rivers Headwaters (TRH) region has changed significantly. In this study, NPP was assessed by Carnegie-Ames-Stanford approach (CASA) model TRH from 2000 to 2019. The abrupt changes and meteorological factors were analyzed cumulative departure, MK test, Pettitt test. contributions human quantitatively using sce...
