Abstract The demand for effective methods to augment precipitation over arid regions of India has been increasing the past several decades as changing climate brings warmer average temperatures. In fourth phase Cloud Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX IV), a scientific investigation was conducted rain-shadow region Western Ghats mountains in India. primary objective investigate efficacy hygroscopic seeding convective clouds develop cloud protocol. CAIPEEX...
Abstract Surface raindrop size distributions over a rain shadow region during the Indian summer monsoon are clustered using k‐means algorithm. The rainfall for five dominant clusters has distinct vertical features in polarimetric radar and micro radar. deep convection with low cloud bases high liquid water is associated sharply increasing reflectivity at levels largest drops surface. large drops, originated by ice processes, break while falling below melting layer, causing peak raindrops...
Abstract. Thermodynamic soundings for pre-monsoon and monsoon seasons from the Indian subcontinent are analysed to document differences between convective environments. The environment features more variability both near-surface moisture free-tropospheric temperature profiles. As a result, level of neutral buoyancy (LNB) pseudo-adiabatic available potential energy (CAPE) vary environment. Pre-monsoon also feature higher lifting condensation levels (LCLs). LCL heights shown depend on...
Abstract General Circulation Models (GCMs) have for decades exhibited difficulties in modelling the diurnal cycle of precipitation (DCP). This issue can be related to inappropriate representation processes controlling sub‐diurnal phenomena like convection. In this study, 11 single‐column versions GCMs are used investigate interactions between convection and environmental conditions, that control nocturnal convections, transition from shallow deep on a time‐scale. Long‐term simulations...
This study reports on new particle formation (NPF) and characteristic features observed from a rural site falling in the rainshadow of Western Ghats peninsular India. A total 35 NPF events during August 2018 - January 2019 are classified analyzed here. The apparent rates ranged 0.2 to 10.0 cm–3 s–1, while growth nucleation mode particles 1.2 13.8 nm h–1. frequency occurrence was least (core monsoon) highest post-monsoon. local winds were calm southeasterly easterly (from urban centre)...
Abstract. Continuous aerosol and cloud condensation nuclei (CCN) measurements carried out at the ground observational facility situated in rain-shadow region of Indian subcontinent are illustrated. These observations were part Cloud Aerosol Interaction Precipitation Enhancement Experiment (CAIPEEX) during summer monsoon season (June to September) 2018. Observations classified as dry–continental (monsoon break) wet–marine active) according air mass history. CCN concentrations measured for a...
