Impact of Temperature Perturbation on the Atmospheric Instability

Abstract

The increase in anthropogenic activities due to large-scale urbanization and industrialization causes unprecedented changes in atmospheric conditions. Several studies reported anthropogenic emissions and their impact on air quality. However, fewer attempts are made to investigate the impact of temperature change due to anthropogenic activity on the Atmospheric Boundary Layer (ABL) and atmospheric instability processes. In this present study, the impact of temperature perturbation due to anthropogenic heating on atmospheric instability (Convective Available Potential Energy (CAPE) and Convective Inhibition Energy (CIN)) is studied exclusively by using the WRF model. Two main CAPE seasons are identified in the study. A high value of CAPE is observed in the monsoon season, and a low CAPE is observed in the pre-monsoon season. Even if a lower value of CAPE does not guarantee deep moist convection in pre-monsoon as more CIN is present. � 2024 IEEE.
