Temperature Projections over the Indus River Basin of Pakistan Using Statistical Downscaling

نویسندگان

چکیده

We assessed maximum (Tmax) and minimum (Tmin) temperatures over Pakistan’s Indus basin during the 21st century using statistical downscaling. A particular focus was given to spatiotemporal heterogeneity, reference General Circulation Model (GCM) uncertainties, skills of regression models an observational profile that could significantly be improved by recent high-altitude observatories. First, we characterized into homogeneous climate regions K-means clustering. Predictors from ERA-Interim reanalysis were then used model observed skillfully quantify GCM uncertainties. Thermodynamical (dynamical) variables mainly governed The predictors under RCP4.5 RCP8.5 scenarios as “new” in project ensemble temperature changes. Our analysis projected non-uniform warming but not validate elevation-dependent (EDW) at scale. obtained more significant westerly-dominated seasons, with heating winter season through Tmin most striking feature is a low-warming monsoon (with possibility no change slight cooling) Upper Basin (UIB). Therefore, likelihood continuing anomalous UIB behavior primary melt may entirely ruled out end RCP8.5.

Sensitivity of glacier runoff projections to baseline climate data in the Indus River basin

Quantifying the contribution of glacier runoff to water resources is particularly important in regions such as High Mountain Asia, where glaciers provide a large percentage of seasonal river discharge and support large populations downstream. In remote areas, direct field measurements of glacier melt rates are difficult to acquire and rarely observed, so hydro-glaciological modeling and remote ...

Retrieval of Land Surface Temperature over the Heihe River Basin Using HJ-1B Thermal Infrared Data

The reliable estimation of spatially distributed Land Surface Temperature (LST) is useful for monitoring regional land surface heat fluxes. A single-channel method is developed to derive the LST over the Heihe River Basin in China using data from the infrared sensor (IRS) onboard the Chinese “Environmental and Disaster Monitoring and Forecasting with a Small Satellite Constellation” (HJ-1B for ...

Evaluation of Reservoir Properties Using Wireline Logs of Well Sarai-Sidhu-1, Punjab Platform, Central Indus Basin, Pakistan

The well Sarai Sidhu-01 is located on Punjab Platform, Central Indus Basin, Pakistan. Punjab Platform is the eastern part of Central Indus Basin, and tectonically it is the stable portion of Indus Basin, which was least affected during Tertiary Himalayan orogeny. This study attempts to decipher reservoir potential for hydrocarbon exploration. It aims to delineate a subsurface hydrocarbon bearin...

Climate change projection of snowfall in the Colorado River Basin using dynamical downscaling

[1] Recent observations show a decrease in the fraction of precipitation falling as snowfall in the western United States. In this work we evaluate a historical and future climate simulation over the Colorado River Basin using a 35 km continuous 111 year simulation (1969–2079) of the Weather Research and Forecasting (WRF) regional climate model with boundary forcing from the Hadley Centre for C...

Soil moisture retrieval over the Mackenzie River basin using AMSR-E 6.9 GHz brightness temperature

An approach is proposed to estimate soil moisture and to monitor its change from AMSR-E 6.9 GHz passive microwave data acquired over a large northern basin. The lack of in situ direct measurements is a major issue to be resolved to reach the aim of this work. Therefore, “external” ancillary data were used as a surrogate for available measurements. The methodology is based on the inversion of a ...
