چکیده

In this study, projected changes in climate extreme indices defined by the Expert Team on Climate Change Detection and Indices were investigated over Middle East North Africa. Changes daily maximum minimum temperature- precipitation- based analyzed for end of 21st century compared to reference period 1971–2000 using regional model simulations. Regional model, RegCM4.4 was used downscale two different global outputs 50 km resolution under RCP4.5 RCP8.5 scenarios. Results generally indicate an intensification with increasing radiative forcing. particular, increase annual temperatures is more pronounced northern part Mediterranean Basin tropics. High warm nights spell duration all region a tropics are 2071–2100 together decrease or no change cold extremes. According results, total wet-day precipitation dry spells expected century.

Jp1.15 Detected Trends in Extreme Temperature and Precipitation Indices in the Central/eastern European Region

Drought events in a particular region often occur in case of long-term lack of precipitation coinciding with hot weather. Global climate change implies increasing global mean temperature (IPCC, 2001), which may occur due to the increasing average and the modified frequency distribution of temperature values. The main objective of our research is to detect the possible changes of intensity and f...

Projected changes of temperature and precipitation in Texas from downscaled global climate models

Climate change projections, in particular precipitation and temperature under different IPCC future emissions scenarios in Texas, were based on statistically downscaled multi-model ensembles. A comparison of downscaled model results with observations and reanalysis data for the present-day climate shows that all models simulate monthly variations in surface air temperature well (correlation coe...

Assessment of Spatial and Temporal Variability of Extreme Precipitation Indices (North and West of Iran)

The frequency of precipitation extreme event can cause flood or change the drought period. Accurate understanding of these changes is necessary to take action to reduce these effects. In this research, temporal and spatial changes of 14 precipitation indices for eight synoptic stations in the North and West of the country were investigated. For this purpose, after reconstructing the daily preci...
