Improved Gravity Wave Drag to Enhance Precipitation Simulation: A Case Study of Typhoon In-Fa

open access: yesAtmosphere, 2023
Traditional gravity wave drag parameterizations produce wind stresses that are insensitive to changing horizontal resolution in numerical weather prediction (NWP), partly due to the idealized elliptical assumption. This study employs the modified subgrid-

Cellular Automata and Markov Chain Based Urban Growth Prediction

open access: yesInternational Journal of Environment and Geoinformatics, 2021
The urban share of the Indian population jumped from 18% in 1961 to 31.16% in 2011 (Gupta et.al2013). This huge spurt in growth of the population is putting a huge demand on available land resource.
