DOI: 10.1029/2021gl094382
Abstract: Convection is highly active on tropical islands. Based on a 3‐year radar climatology over Hainan Island, a mountainous tropical island in South China, we identified a distinct spatial dependence of convection initiation (CI) on the… read more here.

DOI: 10.1175/mwr-d-17-0159.1
Abstract: AbstractThis study tests the hypothesis that assimilating mid- to upper-tropospheric, meso-α- to synoptic-scale observations collected in upstream, preconvective environments is insufficient to improve short-range ensemble convection initiation (CI) forecast skill over the set of cases… read more here.

DOI: 10.1175/mwr-d-20-0118.1
Abstract: Nocturnal convection is often initiated by mechanisms that cannot be easily observed within the large gaps between rawinsondes or by conventional surface networks. To improve forecasts of such events, we evaluate the systematic impact of… read more here.
