Convective Instability Associated with the Eastward-Propagating Rainfall Episodes over Eastern China during the Warm Season
TLDR
In this paper, an analysis of the latest satellite rainfall and reanalysis datasets from 1998 to 2012 demonstrates that eastward-propagating rainfall episodes, which typically occur in late night and early morning, are determinant factors for the rainfall diurnal cycle and climate anomalies over eastern China.Abstract:
Analysis of the latest satellite rainfall and reanalysis datasets from 1998 to 2012 demonstrates that eastward-propagating rainfall episodes, which typically occur in late night and morning, are determinant factors for the rainfall diurnal cycle and climate anomalies over eastern China. The episode growth and propagation are facilitated by an elevated layer of conditionally unstable air in a mesoscale zone at their eastern leading edge. The convective available potential energy (CAPE), despite convection consumption and nocturnal cooling, decreases only from a high value to a moderate one during episode duration. An estimate of the CAPE generation budget suggests that low-level horizontal advection and vertical lifting of the warm moist air can produce sufficient CAPE to balance other stabilization effects, sustaining the mesoscale maximum of convective instability ahead of rainfall episodes. These instability geneses are pronounced at the convection growth stage and linked closely to a mesoscale ...read more

Diurnal Cycle of a Heavy Rainfall Corridor over East Asia
TL;DR: In this article, the authors examined the mechanisms governing nocturnal convection in the southwesterly monsoon that formed over southern China and extended to central China and showed that the NLLJ acted as a mechanism of moisture transport over the plains.

Inferences of Predictability Associated with Warm Season Precipitation Episodes
TL;DR: In this paper, a radar-based climatology of warm season precipitation "episodes" is presented, defined as time-space clusters of heavy precipitation that often result from sequences of organized convection such as squall lines, mesoscale convective systems, and mesoscal convective complexes.
