Finescale Radar Observations of a Dryline during the International H 2 O Project ( IHOP 2002 )
A case study of a double dryline on 22 May 2002 is presented. Mobile, 3-mm-wavelength Doppler radars from the University of Massachusetts and the University of Wyoming (Wyoming cloud radar) were used to collect very fine resolution vertical-velocity data in the vicinity of each of the moisture gradients associated with the drylines. Very narrow (50–100 m wide) channels of strong upward vertical...
متن کاملA . 2 a Multi - Doppler Analysis of Convective Initiation on 10 June 2002 during Ihop _ 2002
Forecasts of the initiation of deep moist convection are important in a variety of meteorological applications: flash flood, severe storm, and quantitative precipitation forecasting. Determining where and when convection occurs affects the aircraft and agriculture industries as well as the general public. Recently, the research community has placed a strong emphasis on factors that determine th...
متن کاملA High-Resolution Modeling Study of the 24 May 2002 Dryline Case during IHOP. Part I: Numerical Simulation and General Evolution of the Dryline and Convection
Results from a high-resolution numerical simulation of the 24 May 2002 dryline convective initiation (CI) case are presented. The simulation uses a 400 km 700 km domain with a 1-km horizontal resolution grid nested inside a 3-km domain and starts from an assimilated initial condition at 1800 UTC. Routine as well as special upper-air and surface observations collected during the International H2...
متن کامل12a.3 a High-resolution Modeling Study of Convective Initiation on 19 June 2002 during Ihop
Accurate prediction of warm-season convective rainfall has remained a challenging problem in the United States. At present, the quantitative precipitation forecasting (QPF) skill associated with these warmseason systems is still very low (Fritsch and Carbone 2004). It is an essential step to improve the QPF skill by improving the knowledge of the timing, location and intensity of convective ini...
متن کاملA High-Resolution Modeling Study of the 24 May 2002 Dryline Case during IHOP. Part II: Horizontal Convective Rolls and Convective Initiation
In Part I of this paper, the timing and location of convective initiation along a dryline on 24 May 2002 were accurately predicted, using a large 1-km-resolution nested grid. A detailed analysis of the convective initiation processes, which involve the interaction of the dryline with horizontal convective rolls, is presented here. Horizontal convective rolls (HCRs) with aspect ratios (the ratio...
