The Formation of Wider and Deeper Clouds as a Result of Cold-Pool Dynamics
Publisher: American Meteorological Society
Abstract: his study investigates how precipitation-driven cold pools aid the formation of wider clouds that are essential for a transition from shallow to deep convection. In connection with a temperature depression and a depletion ...
Mountain Volume Control on Deep-Convective Rain Amount during Episodes of Weak Synoptic Forcing
Publisher: American Meteorological Society
Abstract: Thermally driven upslope flows in mountainous areas provide favorable conditions for diurnal deep moist convection especially during episodes of weak synoptic forcing. The present study investigates the response of deep ...
Idealized Large-Eddy and Convection-Resolving Simulations of Moist Convection over Mountainous Terrain
Publisher: American Meteorological Society
Abstract: n summertime fair-weather days, thermally driven wind systems play an important role in determining the initiation of convection and the occurrence of localized precipitation episodes over mountainous terrain. This study ...
Influence of the Background Wind on the Local Soil Moisture–Precipitation Feedback
Publisher: American Meteorological Society
Abstract: he importance of soil moisture anomalies on airmass convection over semiarid regions has been recognized in several studies. The underlying mechanisms remain partly unclear. An open question is why wetter soils can result ...
Disentangling the Forcing Mechanisms of a Heavy Precipitation Event along the Alpine South Side Using Potential Vorticity Inversion
Publisher: American Meteorological Society
Abstract: Extreme precipitation events along the Alpine south side (AS) are often forced by upper-level positive potential vorticity (PV) anomalies over western Europe. These so-called PV streamers go along with a dynamical forcing ...
An Idealized Cloud-Resolving Framework for the Study of Midlatitude Diurnal Convection over Land
Publisher: American Meteorological Society
Abstract: his paper introduces an idealized cloud-resolving modeling (CRM) framework for the study of midlatitude diurnal convection over land. The framework is used to study the feedbacks among soil, boundary layer, and diurnal ...
