Role of multiscale atmospheric conditions in the evolution of convective organization during MJO-1 of DYNAMO/CINDY/AMIE
… multiscale atmospheric conditions and changes in convective organization during a central Indian Ocean Madden-Julian Oscillation (MJO) event observed by the DYNAMO/CINDY/AMIE field campaigns in October 2011. Shifts in reflectivity and dual-polarization characteristics of four precipitation types …

Interaction between water vapor, radiation and convection in the tropics
… the Equator remains poorly understood because convective organization simultaneously spans the cloud scale (~ 10km) and the planetary scale (~ 10, 000km). Spatiotemporal variability of tropical water vapor may result from internal instabilities of the atmosphere, arising from the interaction …

Convective Dynamics of the Tropical Atmosphere in Three Idealized Approaches
… Earth's climate. Tropical cyclones, mesoscale convective complexes, heat lows, and the rainbands of the Intertropical Convergence Zone are all examples of such large-scale convective organization, but despite their relevance for human life and ecosystems, the mechanisms that govern their …

Radiative feedbacks in tropical organized convection and the Madden-Julian oscillation
The organization of tropical deep convection is supported by radiative feedbacks, in which high clouds and moisture anomalies associated with convection imposes anomalous longwave (LW) radiative heating in the atmosphere, further supporting convection. Despite an abundance of studies using …

Multi-scale interactions leading to tropical cyclogenesis in sheared environments
… a wide range of scales from the stochastic convective scale to a quasi-balanced large-scale flow. This dissertation examines the factors that increase uncertainty around the multi-scale tropical cyclogenesis problem, namely, vertical wind shear (VWS), environmental humidity, and convective …

Understanding the Characteristics of Precipitation and Their Response to Climate Change
… 2-dimensional conceptual model to study tropical convective organization. The model uses the column moist static energy (CMSE) as a prognostic variable and has terms parameterized by diagnosing a high-resolution simulation with explicit convection. Through analyzing the conceptual model, I show …

Analysis of precipitation and convection in the west Pacific during the PISTON field campaign
… size (isolated, sub-MCS, MCS) and degree of convective organization (nonlinear, linear). It is shown that although large mesoscale convective systems (MCSs) occurred infrequently (present in 13% of radar scans), they contributed a disproportionately large portion (56%) of the total rain …
