Simulation of Indian Summer Monsoon Rainfall (ISMR) with fully coupled regional chemistry transport model: A case study for 2017

چکیده
The Indian subcontinent is a major hotspot of enhanced aerosol loading and emission various chemical compounds due to extensive anthropogenic activities that profoundly impact the hydrological cycle this region. Using coupled regional atmospheric chemistry transport model, WRF-Chem (Weather Research Forecasting model with chemistry) fully interactive dynamics, we carried out two sets 122-days simulation experiments: (1) control experiment without embedding (2) sensitivity MOZART-MOSAIC chemistry, examine on Summer Monsoon Rainfall (ISMR) 2017. results show inclusion in plays role altering spatial distribution ISMR, reflected by reduced mean rainfall about 3 mm/day over subcontinent. bias simulated reduces from 2.73 (excluding 1.6 (including chemistry), 1.2 0.81 when compared IMD (India Meteorological Department) TRMM (Tropical Measuring Mission) data, respectively. Additionally, found causes decrease daily convective mm contributing largely differences. Further, analysis hydrometeors indicates interacts cloud microphysics modulating hydrometeor paths different consequently impacts ISMR Results indicate virtue detailed more realistic representation has led cannot be ignored numerical forecasting ISMR.

متن کاملThe Indian summer monsoon rainfall: interplay of coupled dynamics, radiation and cloud microphysics
The Indian summer monsoon rainfall (ISMR), which has a strong connection to agricultural food production, has been less predictable by conventional models in recent times. Two distinct years 2002 and 2003 with lower and higher July rainfall, respectively, are selected to help understand the natural and anthropogenic influences on ISMR. We show that heating gradients along the meridional monsoon...
متن کاملAdvancing Indian Monsoon Rainfall Predictions
Despite great strides made in seasonal climate forecasting using dynamical models, skill in predicting the Indian monsoon is woefully poor. Our analysis of the reasons for failure exposes a flaw in the popular design of dynamical prediction systems. The approach of driving atmospheric models with a projected ocean surface temperature presupposes Indian monsoon variability to be a consequence so...
