Precipitation during 2001-2016 over the northern and central part of Tuscany was studied in order to characterize the rainfall regime. The dataset consisted of hourly cumulative rainfall series recorded by a network of 801 rain gauges. The territory was divided into 30x30 km square areas, the annual, seasonal and daily Average Cumulative Rainfall (ACR) in all areas was estimated along with its ...

Rain-fed food crop production is very sensitive to climate variability. The majority of Ethiopian population reliant on rain-fed seasonal agriculture, which the backbone country’s economy. objective study was investigate impact rainfall and temperature changes maize sorghum yields. data were analyzed using Mann–Kendall trend test, Sen’s slope, correlation, regression models. study’s findings de...

while the hydrological balance of forest ecosystems has often been studied, quantitative studies on the seasonal variability of rainfall interception (i) and canopy storage capacity (s) by individual trees are less frequently reported. hence, the effects of the seasonal variation in i and s by individual persian oak trees (quercus brantii var. persica) in the zagros forests of iran were studied...

Interannual variability of seasonal rainfall in the Brazilian Amazon basin is examined in context of its relationship to sea surface temperatures in the tropical Pacific and Atlantic Oceans. Linear correlations reveal strong relationships, but rainfall patterns are of regional scale. Areas of rainfall exhibiting strong relationships with SST are confined to the equatorial region of the Brazilia...

This article aims to review studies pertaining to trends in rainfall, rainy days and temperature over India. Sen’s non-parametric estimator of slope has been frequently used to estimate the magnitude of trend, whose statistical significance was assessed by the Mann–Kendall test. Spatial units for trend analysis vary from station data to sub-division to sub-basin/ river basins. There are differe...

The primary goal of the Florida Atmospheric Mercury Study (FAMS) was to quantify the atmospheric deposition of Hg throughout Florida. Monthly integrated precipitation and weekly integrated particulate samples were collected at 10 sites in Florida for periods ranging from 2 to 5 yr. The monthly rainfall across the state and the concentrations of Hg in wet-only and bulk deposition increased by a ...

Extreme rainfall events are a serious concern for regional hydrology and agriculture in the Ebro River Basin. Repeated anomalous rainfall in recent decades has had a devastating impact on this region, both socially and economically. Some studies developed in Italy and USA have shown that there is a change in seasonal patterns and an increasing frequency of extreme rainfall events, whereas other...

Abstract Scientists, since a long time, have paid attention on climate change and, in particular, rainfall decrease. These changes resulted modifications of the regime many Mediterranean regions. This work is based monthly data from 17 stations located Tafna catchment (North West Algeria). The study aim to identify long-term (1970–2016) spatial and temporal trends annual, seasonal precipitation...
