The prediction of two cases of severe convection: implications for forecast guidance
Severe convection in the Sydney basin regularly produces destructive winds, heavy rain or flash flooding, and damage from large hail.
Initial work has been carried out that examines two cases of severe convection in the Sydney basin.
The model results discriminated well between severe convection that actually did occur in the first case (1 December, 2000) and the failure of severe convection to develop in the second case (8 December, 2000).
The operational forecasters predicted severe convection to occur in both cases.
The difference is examined in atmospheric circulation and Sea Surface Temperatures (SSTs) in the trop-ics and subtropics between weak and strong convection over the tropical western Pacific warm pool (signified as WPWP).
A composite study was carried out to examine the differences in atmospheric circulation and SSTs between weak and strong convection over WPWP.
A simulation study of ionization depletion in the auroral ionosphericF-region caused by strong convection electric field
THe effects of strong convection electric field on the electron density in the auroral ionosphericF-region have been simulated numerically by means of a physical model.
The strengthened meridional temperature gradient enhances the Asian summer monsoon circulation and favors the strong convection.
The influence of horizontally non-uniform heating upon the development of strong convective mesoscale disturbances
It is shown by observational data and synoptic analysis that the development of strong convective echo is influenced by the horizontally non-uniform heating, such as the one caused by lake-land distribution.
One of the intriguing findings which accords well with observations demonstrates that cold currents create strong convective weather, while warm currents bring about stable weather: produce prolonged low clouds or fogs.
After onset of the SW monsoon the strong convective area moves northwards, while the SCS rain band moves to the center and north.
It is found that strong convective cells with reflectivity greater than 30dBZ mainly are situated in the front region of hailstorms, whereas the trailing stratiform region is in the rear part of the hailstorms.
