The Indian summer monsoon rainfall (ISMR) exhibits significant variability, affecting the food and water security of densely populated subcontinent. two dominant spatial modes ISMR variability are associated with El Niño Southern Oscillation (ENSO) strength semi-permanent trough along related in depressions, respectively. Although robust teleconnection between ENSO has been well established for several decades, major drivers leading to time-varying relationship patterns across different...

Cyclone Fani, in April 2019, was the strongest pre-monsoon cyclone to form Bay of Bengal after 1994. It underwent rapid intensification and intensified quickly an extremely severe cyclone. maintained a wind speed ≥ 51 m s-1 (≥ 100 knots) for record time period 36 h. The total lifespan double than climatological lifespan. Also, duration its phase accumulated energy were significantly larger records season. In current study, we investigate ocean-atmospheric conditions that led genesis, long...

Warmer sea surface temperatures (SSTs) increase evaporation, convection, and latent heat release in the atmosphere, which favors tropical cyclone (TC) intensification ultimately leads to stronger storms. However, this study, we find that intensity of TCs western North Pacific, called typhoons, is on average higher colder autumn season than during warmer summer season. The primary reason for despite decrease SSTs autumn, deepening ocean mixed layer TC potential reduces storm-induced SST...

Cyclone Ockhi in November 2017, was the first very severe cyclone to form over Lakshadweep Sea since 1925, resulting a death toll of 844 India and Sri Lanka.The distance travelled, duration accumulated energy were significantly larger for Ockhi, comparison with climatological records.It intensified rapidly from depression span 9 h further 24 h.The present study shows that Madden-Julian Oscillation warm oceanic conditions provided favourable dynamic thermodynamic genesis Ockhi.The due...

Abstract Generally, monsoon conditions are unfavourable for cyclogenesis in the Arabian Sea due to strong vertical wind shear present over basin which prevents development of cyclones. However, there instances where tropical cyclones form during onset phase Indian summer (ISM). The current study examines evolution synoptic years 1979–2019 a cyclone forms ISM. effect various atmospheric and oceanic factors, modulation circulation subcontinent north Ocean region possible influence...

Abstract Tropical cyclone (TC)‐induced sea surface temperature (SST) cooling plays an important role in controlling the intensity of TCs ocean basins and can modulate local weather. This study examined seasonal differences TC‐induced SST cooling, especially between summer (June–August) autumn (September–November), western North Pacific for period 1992–2021. The analysis shows that average maximum along TC track is 0.18°C less than summer, although mean 14 knots higher summer. because autumn,...

India is a country that has an abundant amount of solar energy.Air Heating famous application energy.The heated air can be used in industry number like crop drying, wood seasoning and refinery.The Solar Air Heater the device which for heating with help energy.In this study, two designs heatesr analyzed compared.The first design consists triangular fins produced over absorber plate second one tin pipes fixed plate.The comparison both heaters was made based on Heat transfer rate, efficiency,...

Abstract The cyclones during November in the Bay of Bengal follow two distinct tracks. Analysis for period 1982–2019 shows that some move west‐northwestward and make landfall at Odisha, Andhra Pradesh or Tamil Nadu coast India, Sri Lanka coast, while others north‐northeastwards West Bengal, Bangladesh Myanmar coast. Our analysis there is a significant difference steering winds governing these different cyclone north‐northeastward moving are associated with an anomalous upper‐level cyclonic...

Abstract The Indian summer monsoon rainfall (ISMR) exhibits significant variability, affecting the food and water security of densely populated subcontinent. two dominant spatial modes ISMR variability are associated with El Niño Southern Oscillation (ENSO) strength semi-permanent trough related in depressions, respectively. ENSO strongly influences ISMR, but temporal regional this teleconnection is not well understood. Our analysis shows that between increased consistently 1901 to 1940,...

Abstract Aerofoil with anti-singing trailing edge has been seen as the treatment to eliminate singing. The present study numerically investigates bevel and chamfer edges rounded ones in flat plates. effects of 25°, 45°, 10° 15°, 45° angles provided at plate on aerodynamic characteristics are systematically compared a Reynolds number 1.5x10 5 30° angle attack. substantial reduction primary vortex shedding frequency is observed one. Also, presence broader wake profile indicates higher drag...

A relational database of codons, corresponding amino acid sequence and the protein conformation in terms dihedral angles, "Cod-ConfDB" has been developed considering well- resolved representative proteins data bank (PDB). In other words, provides information at three levels viz. nucleotide level (codons), primary structure (amino sequence) three-dimensional (conformation protein). The is Web accessible can be queried through interface. would have numerous applications including optimization...

<p>Tropical cyclones in the north Indian Ocean evolve differently response to SST changes during pre-monsoon (April-June) and post-monsoon (October-December) cyclone season. We analyzed for period 1982–2019 observed that there is a contrasting ocean-atmosphere two seasons. During season, anomalous large SSTs along with high near-surface moisture disequilibrium higher winds enhance latent heat flux exchange from ocean atmosphere. This increase enhances convection...

Cyclones in the north Indian Ocean evolve differently during pre-monsoon (April-June) and post-monsoon (October-December) seasons. While several studies have investigated near-surface ocean-atmospheric interactions, there is a lack of understanding upper-atmospheric response cyclones. In current study, we find that cyclones this basin induce warming 3–4°C at upper tropospheric levels (300–400 hPa) season, for period 1982–2019. However, upper-level only ~1°C. The contrasting atmospheric to...
