ERA5 is the fifth-generation atmospheric reanalysis of European Center for Medium-Range Weather Forecasts, with high spatiotemporal resolution and global coverage. However, reliability simulating extreme precipitation events still unclear over China. In this study, 12 indices a comprehensive quantitative distance between simulation observation were used to evaluate from three fundamental aspect...

Precipitation change has significantly influenced annual net primary productivity (ANPP) at either annual or seasonal scales in desert steppes in arid and semi-arid regions. In order to reveal the process of precipitation driving ANPP at different time scales, responses of different ANPP levels to the inter-annual and intra-annual precipitation fluctuations were analyzed. ANPP was reversed by b...

In this paper we examined whether the recorded precipitation changes cause erosion in Naxos Island, Greece using precipitation indices derived from daily precipitation totals, during the period 1955–2007, in order to develop an erosion risk model. Although the mean annual precipitation appear to be low (∼360.0 mm), the erosion processes of the area are very intense, because of the intensive cha...

In this study, the relationship between annual sunspot number (ASN) and annual precipitation totals (APT) has been investigated over the northern coasts of the Persian Gulf and Oman Sea by using two statistical methods: contingency tables and cross-correlation function. Only Bushehr and Jask stations (270 mm and 140 mm mean APT) have long term monthly precipitation records started instrumentall...

Spatially distributed monthly evapotranspiration (ET) rates over the 2000–2009 period were specified for the three states [Colorado (CO), Kansas (KS), Nebraska (NE)] sharing the Republican River basin with the help of a calibration-free ETestimation method using Moderate Resolution (of about one km) Imaging Spectroradiometer (MODIS) data. Mean annual ET rate is 444 mm [i.e., 103% of the mean an...

with respect to wide distribution of a. sieberi besser in iran, various studies have been done on its habitats and different ecological properties have been referred as effective factors in establishment of this species. in this research, we tried to study the ecological range of a. sieberi and its relationship with vegetative characteristics. therefore, climate properties including annual prec...

Gridding of daily precipitation data alleviates many of the limitations of data that are derived from point observations, such as problems associated with missing data and the lack of spatial coverage. As a result, gridded precipitation data can be valuable for applied climatological research and monitoring, but they too have limitations. To understand the limitations of gridded data more fully...

In this paper, a study of the statistical analysis of total ozone concentration as released by satellite EPTOMS was used to show that annual coefficient of relative variability (ACRV) of ozone in West Africa over a period of 48 months increased gradually from 3.5% at latitudinal zone 0-5N to 6.1% at zone 2025N. A strong positive correlation of 0.99 was observed between the ACRV of ozone and ave...

Monthly and 3-hourly precipitation data from twentieth-century climate simulations by the newest generation of 18 coupled climate system models are analyzed and compared with available observations. The characteristics examined include the mean spatial patterns, intraseasonal-to-interannual and ENSO-related variability, convective versus stratiform precipitation ratio, precipitation frequency a...

Groundwater abstraction and depletion were assessed at a 1-km resolution in the irrigated areas of the Indus Basin using remotely sensed evapotranspiration (ET) and precipitation; a process-based hydrological model and spatial information on canal water supplies. A calibrated Soil and Water Assessment Tool (SWAT) model was used to derive total annual irrigation applied in the irrigated areas of...
