Abstract Properly capturing the transition from shallow to deep convection remains a major shortcoming of numerical weather and climate models due to poor understanding of the physical processes controlling this transition. Although recent studies su

Convective rolls are two-dimensional convective quasi-lines that can strongly influence phenomena associated with severe weather. They can also influence the urban micro-climate by increasing the surface wind shear. In this study, we aim to theoretic

The aim of this work is to present a theoretical scheme of dry thermal convection and convective rolls in atmospheric boundary layer with a linear eddy viscosity for a steady-state stationary case. For this theoretical study, a few approximations val

Analytical solution for two-dimensional thermal plume updraft velocity is obtained under the assumption of a uniform temperature excess inside the plume. In this way, the thermal plume motion is modeled in both mixed layer and entrainment zone. Also,

A forecasting scheme of the thermal updraft velocity based on a theoretical model and data collected from flights records at gliding competitions, is presented. The forecasting scheme was based on the hypothesis that there is linear relationship betw
