Simulation of rain-bearing summer monsoon systems along the west coast of India by use of ARMEX re-analysis

Gupta, M. Das; Pradhan, P.; Das, Someshwar; Mohanty, U. - In: Natural Hazards 42 (2007) 2, pp. 379-390

Re-analysis, using surface, upper-air, and satellite observations specially collected during the Arabian Sea Monsoon Experiment-I (ARMEX-I), has been performed with a global data assimilation system at T-80/L18 resolution. Re-analysis was performed for the entire ARMEX-I period (15th June–16th...

Influence of different land-surface processes on Indian summer monsoon circulation

Singh, A.; Mohanty, U.; Sinha, P.; Mandal, M. - In: Natural Hazards 42 (2007) 2, pp. 423-438

The impact of different land-surface parameterisation schemes for the simulation of monsoon circulation during a normal monsoon year over India has been analysed. For this purpose, three land-surface parameterisation schemes, the NoaH, the Multi-layer soil model and the Pleim-Xiu were tested...

Temporal characteristics of the Indian southwest monsoon

Rao, P.; Mohanty, U. - In: Natural Hazards 42 (2007) 2, pp. 335-344

In this study, we elucidate the temporal characteristics of the onset and withdrawal of the Indian southwest monsoon, making use of the model integration and daily analyses of the National Centre for Medium Range Weather Forecasting, India. The onset of the Indian southwest monsoon over the Bay...

Performance of general circulation models and their ensembles for the prediction of drought indices over India during summer monsoon

Acharya, Nachiketa; Singh, Ankita; Mohanty, U.; Nair, … - In: Natural Hazards 66 (2013) 2, pp. 851-871

The drought during the months of June to September (JJAS) results in significant deficiency in the annual rainfall and affects the hydrological planning, disaster management, and the agriculture sector of India. Advance information on drought characteristics over the space may help in risk...

Simulation of Orissa Super Cyclone (1999) using PSU/NCAR Mesoscale Model

Mohanty, U.; Mandal, M.; Raman, S. - In: Natural Hazards 31 (2004) 2, pp. 373-390

In this study a non-hydrostatic version of Penn State University (PSU) -- NationalCenter for Atmospheric Research (NCAR) mesoscale model is used to simulate thesuper cyclonic storm that crossed Orissa coast on 29 October 1999. The model isintegrated up to 123 h for producing 5-day forecast of...

Impact of Doppler weather radar data on thunderstorm simulation during STORM pilot phase—2009

Prasad, S. Kiran; Mohanty, U.; Routray, A.; Osuri, Krishna - In: Natural Hazards 74 (2014) 3, pp. 1403-1427

This study assesses the impact of Doppler weather radar (DWR) data (reflectivity and radial wind) assimilation on the simulation of severe thunderstorms (STS) events over the Indian monsoon region. Two different events that occurred during the Severe Thunderstorms Observations and Regional...

On the exact and phenomenological Langevin equations for a harmonic oscillator in a fluid

Mohanty, U.; Shuler, K.E.; Oppenheim, I. - In: Physica A: Statistical Mechanics and its Applications 115 (1982) 1, pp. 1-20

We have derived, starting from the Liouville equation and using projection operators, the three-dimensional Langevin and Fokker-Planck equations for the time dependence of the momenta and position of two Brownian particles of mass M interacting with a harmonic potential (i.e., a harmonic...
