Abstract The southern Indian state of Kerala experienced exceptionally high rainfall during August 2018, which led to devastating floods in many parts the state. Prediction and early warning severe weather events vulnerable areas is crucial for disaster management agencies order protect life property. In recent years, state‐of‐the‐art numerical prediction (NWP) models have been used operationally predict over different spatial temporal scales. present paper, predictions based on National...
In this paper, we summarize findings from the Tenth International Workshop on Tropical Cyclones (IWTC-10) subgroup operational track forecasting techniques and capability. The rate of improvement in accuracy official forecast tracks (OFTs) appears to be slowing down, at least for shorter lead times, where may approaching theoretical limits. Operational agencies continue use consensus methods produce OFT with most continuing rely an unweighted four nine NWP models. There continues limited...
Prediction of the potentially devastating impact landfalling tropical cyclones (TCs) relies substantially on numerical prediction systems. Due to limited predictability TCs and need express forecast confidence possible scenarios, it is vital exploit benefits dynamic ensemble forecasts in operational TC warnings. RSMCs, TCWCs, other centers value probabilistic guidance for TCs, but International Workshop Tropical Cyclones (IWTC-9) found that "pull-through" information warnings using those...
The influence of the local sea surface temperature (SST) and remote ENSO (El Niño-Southern Oscillation) indices on wind speed (WS) data were explored for Indian Ocean region. Relationships among parameters studied using spatial correlation plots significant ranges. Two months (July January) representing opposite monsoon phases selected analysis period 1950–2016. There was a negative between WS SST over Bay Bengal (BOB) during July. Although different correlated differently in areas Ocean,...
The coastal wave dynamics of Agatti island situated on a coral atoll in Lakshadweep, India, having notable topographic feature steeper eastern shore over the western shore, is analysed this study. A multinested model setup generated using global third-generation models WAM (Wave Modeling) and SWAN (Simulating Waves Nearshore). high resolution unstructured grid for domain containing SMS (Surface-Water Modeling System) interpolated with merged GEBCO (General Bathymetric Chart Oceans) SRTM...
