Prediction of Extremely Severe Cyclonic Storm “Fani” Using Moving Nested Domain

چکیده
The prediction of extremely severe cyclonic storms has been a long-standing and challenging issue due to their short life period large variation in intensities over time. In this study, we predict the track, intensity, structure an storm (ESCS) named ‘Fani,’ which developed Bay Bengal region from 27 April 4 May 2019, using Advanced Research version Weather Forecasting (WRF-ARW) model. Two numerical experiments were conducted moving nested domain method with 3 km horizontal resolution, one FLUX-1 air-sea flux parameterization scheme other FLUX-2 scheme. NCEP operational Global Forecast System (GFS) analysis forecast datasets 25 resolution used derive initial boundary conditions. WRF model’s predicted track intensity validated best-fit dataset India Meteorological Department (IMD), was different observations. results showed that model accurately landfall (position time), (minimum sea level pressure maximum surface wind) storm. errors on days 1 approximately 47 km, 123 96 experiment 54 142 152 166 experiment, respectively. better during first 60 h, while it for remaining period. structure, terms relative humidity, water vapor, reflectivity, temperature anomaly storm, also discussed compared available satellite Doppler Radar

Real-Time Spatial Queries for Moving Objects Using Storm Topology
With the rapid development of mobile data acquisition technology, the volume of available spatial data is growing at an increasingly fast pace. The real-time processing of big spatial data has become a research frontier in the field of Geographic Information Systems (GIS). To cope with these highly dynamic data, we aim to reduce the time complexity of data updating by modifying the traditional ...
متن کاملPrediction of dispersed mineralization zone in depth using frequency domain of surface geochemical data
Discrimination of the blind and dispersed mineralization deposits is a challenging problem in geochemical exploration. The frequency domain (FD) of the surface geochemical data can solve this important issue. This new exploratory information can be achieved using the interpretation of FD of geochemical data, which is impossible in spatial domain. In this research work, FD of the surface geochem...
متن کاملPrediction of magnetic storm events using the Dst index
This paper provides a method to predict magnetic storm events based on the time series of the Dst index over the period 1981–2002. This method is based on the multiple scaling of the measure representation of the Dst time series. This measure is modeled as a recurrent iterated function system, which leads to a method to predict storm patterns included in its attractor. Numerical results are pro...
متن کاملBiological function integrated prediction of severe radiographic progression in rheumatoid arthritis: a nested case control study
BACKGROUND Radiographic progression is reported to be highly heritable in rheumatoid arthritis (RA). However, previous study using genetic loci showed an insufficient accuracy of prediction for radiographic progression. The aim of this study is to identify a biologically relevant prediction model of radiographic progression in patients with RA using a genome-wide association study (GWAS) combin...
