TL;DR: The Advanced Regional Prediction System of the Center for Analysis and Prediction of Storms at the University of Oklahoma as discussed by the authors was used to predict a series of supercell storms that produced a historical number of tornadoes more than 8 hours in advance to within tens of kilometers in space.

TL;DR: In this paper, a new method of dual-Doppler radar wind analysis based on a three-dimensional variational data assimilation (3DVAR) approach is proposed, where a cost function, including background term and radial observation term, is minimized through a limited memory, quasi-Newton conjugate-gradient algorithm with the mass continuity equation imposed as a weak constraint.

TL;DR: This paper proposes a new method of dual-Doppler radar analysis based on a variational approach, in which a cost function is minimized through a limited memory, quasi-Newton conjugate gradient algorithm with the mass continuity equation imposed as a weak constraint.

TL;DR: The 2010 NOAA/HWT Spring Forecasting Experiment (SE2010), conducted 17 May through 18 June, had a broad focus, with emphases on heavy rainfall and aviation weather, through collaboration with the Hydrometeorological Prediction Center (HPC) and the Aviation Weather Center (AWC), respectively as discussed by the authors.

TL;DR: In this paper, the impact of radar reflectivity and radial velocity data on the prediction of a cluster of tornadic thunderstorms in the Advanced Regional Prediction System (ARPS) model is studied.
