Rainfall is one the main drivers of soil erosion. The erosive force of rainfall is expressed as rainfall erosivity. Rainfall erosivity considers the rainfall amount and intensity, and is most commonly expressed as the R-factor in the USLE model and its revised version, RUSLE. At national and continental levels, the scarce availability of data obliges soil erosion modellers to estimate this fact...
OBJECTIVE Although bipolar disorder has high heritability, the onset occurs during several decades of life, suggesting that social and environmental factors may have considerable influence on disease onset. This study examined the association between the age of onset and sunlight at the location of onset. METHOD Data were obtained from 2414 patients with a diagnosis of bipolar I disorder, acc...
Rainwater harvesting is one of the available, low-cost, and complementary methods for groundwater use, which is highly important in arid and semi-arid regions. The purpose of this study is to estimate the amount of water that can be extracted from the annual rainfall of Aryan Shahr for non-drinking purposes. In this study, in the first stage, the rainfall data of the Aryan Shahr climatology sta...
BACKGROUND Climatic variables can determine malaria transmission dynamics. To see the correlation between malaria occurrence and climatic variables, records of malaria episodes over eight years period were analyzed incorporating climatic variables around Gilgel-Gibe Hydroelectric Dam and control sites. METHODS Records of 99,206 confirmed malaria episodes registered between 2003 and 2011 were ...
A sequential synthesis inversion method is described to estimate CO 2 sources from continuous atmospheric data. The sequential method makes the problem computationally feasible. The method is assessed using four-hourly synthetic concentration data generated from known sources. Multi-year mean sources and seasonal cycles are estimated with comparable quality as those from a traditional inversion...
In this paper, the variation of temperature and rainfall at Patna are analysed using simple non-parametric tests. The trends in annual maximum minimum daily temperatures, rainfall, number rainy days a year, average per day ratio to have been examined. Tends total monthly Highest month also determined for every year. data Mann-Kendall test indicated statistically significant changes pattern city.
The daily rainfall data of 37 years were collected from the IMD approved Meteorological Observatory situated at GB Pant University of Agriculture and Technology, Pantnagar, India. The data were then processed to identify the maximum rainfall received on any one day (24hrs duration), in any week (7 days), in a month (4 weeks), in a monsoon season (4 months) and in a year (365 days period). The d...
Detailed knowledge of rainfall regime is an important prerequisite for agricultural planning. Despite the importance of rain-fed agriculture to food security in the semi-arid regions of South Africa, studies to understand the spatial and temporal variability of rainfall are not widely documented. Twenty-three years (1983 to 2005) of rainfall data were analysed in order to study the basic statis...
