| Abstract: | Clouds modulate the infrared radiation absorption and shortwave radiation reflection in the atmosphere. Infrared absorption inside the cloud generates turbulence and alters the hydrometeor energy distribution. Therefore, it is imperative to parameterize changes in heat, specific vertical momentum, and vertical velocity in microphysical models. This paper aims to parameterize the impact of infrared absorption/heating on vertical velocity inside the cloud for stratiform rainfall on 01-Sep-2019 over Gadanki, India. The line-by-line spectroscopic parameters were obtained from the HITRAN dataset, and the absorption coefficients from surface to 280 hPa have been calculated. Specific moist entropy and advection–diffusion equations have been solved to estimate changes in temperature, moist entropy, specific vertical momentum, and vertical velocity. Results show that infrared heating/cooling (IRH/C) caused a temperature increase (decrease) below (above) 700 hPa. It also caused a negative (positive) change in moist entropy below (above) 700 hPa, which strengthened (suppressed) cloud growth in the lower (upper) layers of the cloud. Change in specific vertical momentum found to be negative, i.e., downdraft/downward momentum transfer below 700 hPa till cloud bottom, and positive, i.e., updraft/upward momentum transfer above 700 hPa till cloud top. The study showed that IRH/C substantially impacts the vertical velocity inside the cloud. Research highlights: The parameterization for estimating the impact of infrared heating and cooling on stratiform cloud evolution has been developed. HITRAN spectroscopic parameters have been used to estimate the vertical profile of infrared radiative properties in the atmosphere. Infrared heating/cooling restricts the cloud's vertical structure by controlling most of the entropy and vertical momentum transfer. The heating/cooling perturbs moist entropy either to positive or negative values, implying evaporation (growth) or melting (decay) of hydrometeors inside the clouds. Infrared heating/cooling significantly perturb the vertical velocity, i.e., updrafts/downdrafts, and hence hydrometeor distribution inside the cloud. [ABSTRACT FROM AUTHOR] |
