Evaluation of Two Initialization Schemes for Simulating the Rapid Intensification of Typhoon Lekima (2019)
Two different initialization schemes for tropical cyclone (TC) prediction in numerical models are evaluated based on a case study of Typhoon Lekima (2019). The first is a dynamical initialization


The Impact of Dry Midlevel Air on Hurricane Intensity in Idealized Simulations with No Mean Flow
AbstractThis study examines the potential negative influences of dry midlevel air on the development of tropical cyclones (specifically, its role in enhancing cold downdraft activity and suppressing
Reevaluating the Role of the Saharan Air Layer in Atlantic Tropical Cyclogenesis and Evolution
Abstract The existence of the Saharan air layer (SAL), a layer of warm, dry, dusty air frequently present over the tropical Atlantic Ocean, has long been appreciated. The nature of its impacts on
Dependence of Tropical Cyclone Intensification on the Latitude under Vertical Shear
The sensitivity of tropical cyclone (TC) intensification to the ambient rotation effect under vertical shear is investigated. The results show that the vortices develop more rapidly with intermediate
Effects of Vertical Shears and Midlevel Dry Air on Tropical Cyclone Developments
AbstractA set of idealized experiments using the Weather Research and Forecasting model (WRF) were designed to investigate the impacts of a midlevel dry air layer, vertical shear, and their combined
Effects of Midlevel Dry Air on Development of the Axisymmetric Tropical Cyclone Secondary Circulation
AbstractIdealized experiments conducted with an axisymmetric tropical cyclone (TC) model are used to assess the effects of midlevel dry air on the axisymmetric TC secondary circulation. Moist entropy
Why Do Model Tropical Cyclones Intensify More Rapidly at Low Latitudes
AbstractThe authors examine the problem of why model tropical cyclones intensify more rapidly at low latitudes. The answer to this question touches on practically all facets of the dynamics and
A Numerical Study of the Impacts of Dry Air on Tropical Cyclone Formation: A Development Case and a Nondevelopment Case
AbstractThe impacts of dry air on tropical cyclone formation are examined in the numerical model simulations of ex-Gaston (2010) and pre-Fay (2008). The former, a remnant low downgraded from a
How Do Outer Spiral Rainbands Affect Tropical Cyclone Structure and Intensity
Abstract A long-standing issue on how outer spiral rainbands affect the structure and intensity of tropical cyclones is studied through a series of numerical experiments using the cloud-resolving
Impact of environmental moisture on tropical cyclone intensification
Abstract. The impacts of environmental moisture on the intensification of a tropical cyclone (TC) are investigated in the Weather Research and Forecasting (WRF) model, with a focus on the azimuthal
Dependence of Tropical Cyclone Intensification on the Coriolis Parameter
ABSTRACT The dependence of tropical cyclone (TC) intensification on the Coriolis parameter was investigated in an idealized hurricane model. By specifying an initial balanced vortex on an f-plane, we
