Wavelet Support Vector Machines for Forecasting Precipitation in Tropical Cyclones: Comparisons with GSVM, Regression, and MM5

, 2011
This study presents two support vector machine (SVM) based models for forecasting hourly precipitation during tropical cyclone (typhoon) events. The two SVM-based models are the traditional Gaussian kernel SVMs (GSVMs) and the advanced wavelet kernel ...

Simulation of Severe Local Storm by Mesoscale Model MM5 and Validation Using Data from Different Platforms

, 2015
During premonsoon season (March to May) convective developments in various forms are common phenomena over the Gangetic West Bengal, India. In the present work, simulation of wind squall on three different dates has been attempted with the help of ...

Verification and Sensitivity Experiments for the WISP94 MM5 Forecasts

Weather and Forecasting, 1997
Abstract A statistical verification of real-time forecasts from the Pennsylvania State University–National Center for Atmospheric Research Mesoscale Model version 5 (MM5) examines several model biases noted in numerical forecasts prepared for the Winter Icing and Storms Project’s 1994 field experiment.

Chemistry in Infrared Dark Cloud Clumps: a Molecular Line Survey at 3 mm

, 2012
We have observed 37 Infrared Dark Clouds (IRDCs), containing a total of 159 clumps, in high-density molecular tracers at 3 mm using the 22-meter ATNF Mopra Telescope located in Australia.

Water vapour distribution at urban scale using high-resolution numerical weather model and spaceborne SAR interferometric data [PDF]

Natural Hazards and Earth System Sciences, 2010
The local distribution of water vapour in the urban area of Rome has been studied using both a high resolution mesoscale model (MM5) and Earth Remote Sensing-1 (ERS-1) satellite radar data.

Influences of Asymmetric Heating on Hurricane Evolution in the MM5

Journal of the Atmospheric Sciences, 2005
Abstract While previous idealized studies have demonstrated the importance of asymmetric atmospheric features in the intensification of a symmetric tropical cyclone vortex, the role of convectively generated asymmetries in creating changes in the azimuthally averaged cyclone is not well understood.

Evaluation of high‐resolution regional CO2 data assimilation–forecast system in East Asia using observing system simulation experiment and effect of observation network on simulated CO2 concentrations

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Develop data assimilation (DA)–forecast system: a system was developed to assimilate surface CO2 concentrations to improve atmospheric CO2 concentration simulations in East Asia. Conduct observing system simulation experiments (OSSEs) and verify stability: OSSEs conducted for January and July 2019 showed that DA reduced the bias and root‐mean‐squared ...

The initial conditions of star formation in the Ophiuchus main cloud: Kinematics of the protocluster condensations [PDF]

, 2007
The earliest phases of clustered star formation and the origin of the stellar initial mass function (IMF) are currently much debated. In order to constrain the origin of the IMF, we investigated the internal and relative motions of starless condensations
