Observation system simulation experiments are used to evaluate different dual-Doppler analysis (DDA) methods for retrieving vertical velocity w at grid spacings on the order of 100 m within a simulated tornadic supercell. Variational approaches with

To investigate the effect of surface drag on tornadogenesis, a pair of idealized simulations is conducted with 50-m horizontal grid spacing. In the first experiment (full-wind drag case), surface drag is applied to the full wind; in the second experi

Non-supercellular damaging winds from convective storms are overwhelmingly associated with quasi-linear convective systems. A review of early studies of these systems suggested that wind damage/speed was not continuous and instead was enhanced over m

Vortex stretching by intense upward accelerations is a critical process for tornadogenesis and maintenance. Two high-resolution (250-m grid spacing) real-data simulations of the 3 May 1999 Oklahoma City, Oklahoma, supercell and associated tornadoes,

A high-resolution simulation of the 8 May 2003 Oklahoma tornadic supercell is analyzed to determine the origin of internal outflow surges within the low-level cold pool. The analyzed simulation has 50-m horizontal grid spacing and is quadruply nested

When the surface temperature is >10°C (50°F) and when the lowest ~2 km (7000 ft) of the atmosphere is entirely >0°C (32°F), ice pellets or any other type of winter precipitation type typically are not expected. However, these were the conditions

The 8 May 2003 Oklahoma City, Oklahoma, tornadic supercell is predicted with the Advanced Regional Prediction System (ARPS) model using four nested grids with 9-km, 1-km, 100-m, and 50-m grid spacings. The Oklahoma City Weather Surveillance Radar-198

A 50-m-grid-spacing Advanced Regional Prediction System (ARPS) simulation of the 8 May 2003 Oklahoma City tornadic supercell is examined. A 40-min forecast run on the 50-m grid produces two F3-intensity tornadoes that track within 10 km of the locati

An iterative procedure is designed to accelerate the ‘spin-up’ of ensemble square-root filter (EnSRF) data-assimilation cycles when starting from a poor initial ensemble. Referred to as the iterative EnSRF (iEnSRF), this iterative procedure follo
