Convection-allowing and convection-parameterizing ensemble forecasts of a mesoscale convective vortex and associated severe weather environment
An analysis of a regional severe weather outbreak that was related to a mesoscale convective vortex (MCV) is performed. The MCV-spawning mesoscale convection system (MCS) formed in northwest Kansas along the southern periphery of a large cutoff 500-hPa low centered over western South Dakota. As the MCS propagated into eastern Kansas during the early morning of 1 June 2007, an MCV that became ev...
متن کاملObject-based evaluation of the impact of horizontal grid spacing on convection-allowing forecasts
Forecasts generated with 1 and 4 km grid spacing using the WRF-ARW model (ARW1 and ARW4, respectively) during the 2009-2011 NOAA Hazadous Weather Testbed Spring Experiments by the Center for Analysis and Prediction of Storms are compared and verified using object-based measures, including average values of object attributes, the Object-based Threat Score (OTS) and the Median of Maximum Interest...
متن کاملSensitivity of desert dust emissions to model horizontal grid spacing during the BodElE Dust Experiment 2005
The impact of model horizontal grid spacing on meteorology and dust emissions in the Bodélé depression was investigated during the well-documented period of the Bodélé Dust Experiment 2005 (BoDEx 2005). Five horizontal grid spacing ranging from 100 km to 5 km were tested. The main conclusion of these sensitivity tests is that the meteorology of the Bodélé depression is quite insensitive to mode...
متن کاملTornadogenesis in a Simulated Mesovortex within a Mesoscale Convective System
TheAdvanced Regional Prediction System (ARPS) is used to simulate a tornadic mesovortex with the aim of understanding the associated tornadogenesis processes. The mesovortex was one of two tornadic mesovortices spawned by a mesoscale convective system (MCS) that traversed southwestern and central Oklahoma on 8–9 May 2007. The simulation used 100-m horizontal grid spacing, and is nested within t...
متن کاملSensitivity of a mesoscale model to different convective parameterization schemes in a heavy rain event
The Valencia region, on the Mediterranean coast of the Iberian Peninsula, is propitious to heavy precipitation, especially the area encompassing the South of Valencia province and the North of the Alicante province. In October 2007 a torrential rain affected the aforementioned area, producing accumulated rainfall values greater than 400 mm in less than 24 h and flash-floods that caused extensiv...
