An analysis of the climatic feedbacks in the NCAR Community Climate Model, version 3 (CCM3) over the equatorial Pacific cold tongue is presented. Using interannual signals in the underlying SST, the radiative and dynamical feedbacks have been calculated using both observations and outputs from the NCAR CCM3. The results show that the positive feedback from the greenhouse effect of water vapor i...

Agricultural residues burning as a means of land preparation commonly practiced in many Southeast Asian countries causes significant deterioration ambient air quality and public health. In this study, WRF-CMAQ Atmospheric Chemical Transport Model was used to conduct year-round simulation (1 January - 31 December 2019) PM2.5 spatio-temporal variation over Asia. The model utilized the Fire emissi...

The Community Atmosphere Model (CAM) has several well known biases that have important dynamical implications for research. Some examples of these biases include a cold temperature bias near the tropopause at high latitudes, systematic biases in the mean zonal wind, and transient momentum fluxes that are too strong. One method for investigating the impacts that these biases have is to use data ...

Significant changes in the Arctic climate, particularly a rapid decline of September sea ice has occurred over past few decades. Though exact reason for such drastic is still unknown, studies suggest anthropogenic drivers, natural variability climate system, and combination both as reasons. The present study focus on influence one variabilities teleconnections associated with Indian Summer Mons...
