Precipitation Trends Analysis in Southwest Asia during the Last Half Century

چکیده مقاله:
Precipitation is a climatic elements that have temporal - spatial distribution. In this research database of Global Precipitation Climatology Centre (GPCC) with a resolution 0.5×0.5 degree for 50 year is used, that was constituted with dimensions of 12800*600. Temporal data are on the columns and pixels (spatial data) located on the rows. The results show an increasing trend in spring and fall but in summer and winter precipitation trend has been decreased. The most amount of precipitation is located in the northern parts of the Black Sea and Mediterranean Sea, Southeast Asia, southern coast of the Caspian and Central Zagros Mountains. Most of Middle East (about %95) have not trend and only in some parts of Kazakhstan, Afghanistan, Pakistan ,central Iran, and areas in lower-latitude have positive trend and some East and northwest parts of Iran and some parts of Middle East also have decreasing trend of precipitation. The highest percent of area of precipitation trend gradient is 0 to 0.5.

Temperature and Precipitation Trends in Canada During the 20th Century
Trends in Canadian temperature and precipitation during the 20th century are analyzed using recently updated and adjusted station data. Six elements, maximum, minimum and mean temperatures along with diurnal temperature range (DTR), precipitation totals and ratio of snowfall to total precipitation are investigated. Anomalies from the 1961–1990 reference period were first obtained at individual ...

متن کاملStatistical Correction of Central Southwest Asia Winter Precipitation Simulations∗
Severe drought is a notable feature of the hydrology of Central Southwest (CSW) Asia. Although studies have linked the region’s interannual precipitation variability to remote forcings that include East Asia Jet Stream variability and Western Pacific tropical convection, atmospheric general circulation models (GCMs) forced by observed sea surface temperatures demonstrate little skill in simulat...
متن کاملRapid decadal convective precipitation increase over Eurasia during the last three decades of the 20th century
Convective precipitation-localized, short-lived, intense, and sometimes violent-is at the root of challenges associated with observation, simulation, and prediction of precipitation. The understanding of long-term changes in convective precipitation characteristics and their role in precipitation extremes and intensity over extratropical regions are imperative to future water resource managemen...
متن کاملANALYSIS OF PRECIPITATION TRENDS DURING 2nd HALF OF THE 20th CENTURY IN AN AREA OF SARDINIA (ITALY) AT HIGH HYDROGEOLOGICAL RISK
We present an analysis of precipitation in an area of Sardinia (Italy) at high hydrogeological risk. Sardinia is an island located in the Western Mediterranean Sea. Precipitation is here a highly irregular phenomenon due to the variability of extra-tropical cyclones. The latitudinal development of the island (~200 Km) gives a climatic North-South gradient. However, the presence of high and stee...
