Abstract:
A detailed study on the distribution of basic cloud types over the northern states of India (NSI) is performed using the decadal (2007–2016) raDAR-liDAR (DARDAR) data, which facilitates merged CloudSat and Cloud aerosol liDAR infrared pathfinder satellite observations (CALIPSO) observations onto the high resolution matched geographical grid points. The study demonstrates the seasonal variations, with south-west monsoon (June–September) exhibiting the maximum (>50%) cloud appearances while during the active period of western disturbances (December–March), ~25% of the total annual clouds, over the NSI region. Altostratus is found to be the most frequent cloud type (~20%) among others in the last decade over this region, while during south-west monsoon and western disturbances, the most dominant cloud types are deep convective (~25%) and nimbostratus (~33%), respectively.
