rainfall spatial analysis methods are very helpful since there are not enough rainfall gauge stations and watersheds are scattered in large extent. there are many different methods for estimating average precipitation such as; arithmetic method and thiessen polygon. however, the arrangement and location of data and their correlations are not considered by classic methods. thus, geostatistical t...

Comparison of single-forcing varieties of 20th century historical experiments in a subset of models from the Fifth Coupled Model Intercomparison Project (CMIP5) reveals that South Asian summer monsoon rainfall increases towards the present day in Greenhouse Gas (GHG)-only experiments with respect to pre-industrial levels, while it decreases in anthropogenic aerosol-only experiments. Comparison ...

The yield of oil palm is heavily influenced by various climatic conditions, including rainfall (RF), radiation (Qs), temperature, and humidity. To quantify the impact these factors, a study was conducted on 15-year-old located in an estate Pangkalan Lima Puluh Kota, West Sumatra, Indonesia. used climate data from 2011-2019 2015 2019. determine contribution RF, Qs, VPD / vapour pressure deficit,...

      Rain gauge stations that measure fine scale rainfall are mainly limited in number or in the length of the recorded data. Therefore, temporal disaggregation models have been considered because of their ability in generating fine scale data from coarse scale measurements of rainfall. In this study, microcanonical cascade model, which is based on the scaling properties of rainfall and consta...

New operational long range forecasting model of India meteorological Department (ImD) is statistical in nature, which has many inherent limitations. The correlation between monsoon rainfall and its predictors can never be perfect. It may suffer epochal changes and there may be a cross correlations among predictors. It is almost impossible to identify appropriate predictors of monsoon rainfall o...

In the present study, the main aim was the spatial evaluation summer rainfall of northwest of Iran based on30 stations in northwest of Iran during 30 years of statistical period (1985-2014). An attempt, using geo-statistical modeling by ordinary least squares (OLS) and geographically weighted regression (GWR) procedures, was also made. The results represented that the GWR model with higher S2, ...

The northern region of Iraq heavily depends on rivers, such as the Greater Zab, for water supply and irrigation. Thus, river water management in light of future climate change is of paramount importance in the region. In this study, daily rainfall and temperature obtained from the Greater Zab catchment, for 1961–2008, were used in building rainfall and evapotranspiration models using LARSWG and...

A statistical approach is used to explore the variability of precipitation and meteorological drought in Mexico’s Rı́o Yaqui basin on seasonal-to-decadal timescales. For this purpose, a number of custom datasets have been developed, including a monthly 1900-2004 precipitation index for the Yaqui basin created by merging two gridded land-surface precipitation products, a 350-year tree-ring based ...
