DOI: 10.1002/2017ms001033
Abstract: The Superparameterized Community Atmosphere Model (SPCAM) is used to identify the dynamical and organizational properties of tropical extreme rainfall events on two scales. We compare the mesoscales resolved by General Circulation Models (GCMs) and the… read more here.

DOI: 10.1002/qj.3785
Abstract: The background error covariance matrix plays a vital role in any data assimilation system. Proper specification, which is determined by the forecast system set‐up, is often required. Previous studies have investigated its relevance in various… read more here.

DOI: 10.1007/s00376-020-9248-x
Abstract: Previous numerical simulations have focused mainly on the mesoscale structure of the principal rainband in tropical cyclones with a relatively coarse model resolution. In this study, the principal rainband was simulated in a semi-idealized experiment… read more here.

DOI: 10.1080/16742834.2019.1548883
Abstract: ABSTRACT In this paper, the authors present the statistical characteristics of the buoyancy of outer-core convective-scale updrafts in numerically simulated sheared tropical cyclones (TCs). The total buoyancy is predominantly positive in weak-to-strong ambient vertical shears,… read more here.

DOI: 10.1175/mwr-d-16-0298.1
Abstract: AbstractParticle filters (PFs) are Monte Carlo data assimilation techniques that operate with no parametric assumptions for prior and posterior errors. A data assimilation method introduced recently, called the local PF, approximates the PF solution within… read more here.
