Abstract: his manuscript introduces a new technique for evaluating lightning forecasts from convection-permitting models. In recent years, numerical weather prediction models at the convection-permitting scales (horizontal grid ...

Abstract: Recent studies have suggested that supercell tornado environments are usually associated with large 0?1-km storm-relative helicity (SRH) and relatively low lifting condensation levels (LCL heights). However, occasional ...

Abstract: It is generally understood that tornadoes are less likely in environments where surface-based instability is absent and the only convective available potential energy (CAPE) is from elevated parcels originating well above ...

Abstract: Tornadoes that occur in close proximity to midlevel closed lows with a core of cold temperatures aloft are not uncommon, particularly in the central United States. Although several informal studies have shown that severe ...

Abstract: n oceanic and atmospheric flows, the eddy vorticity flux divergence?denoted ?F? herein?emerges as a key dynamical quantity, capturing the average effect of fluctuations on the time-mean circulation. For a barotropic system, ...

Abstract: roducing reliable estimates of changes in precipitation at local and regional scales remains an important challenge in climate science. Statistical downscaling methods are often utilized to bridge the gap between the coarse ...

Abstract: AbstractThis study investigates the how riming in stratiform precipitation impacts polarimetric signatures. Using a vertically pointing Doppler X-band radar, cases can be separated into one of three groups: unrimed to ...
