My research has been mainly directed at improving our understanding of mesoscale cloud systems, by means of numerical simulations and analyses of Doppler radar data. Numerical simulations aimed at revealing basic mechanisms involved in the evolutions of cloud systems, so idealized experiments have mainly been conducted using a cloud-resolving model developed by myself. Particular subjects of the numerical modeling study include the self-modulating oscillations in squall-line type convective systems (Kawashima 2003), mechanisms responsible for core/gap structure of narrow cold-frontal rainbands (Kawashima 2007, 2011), and effects of melting-induced cooling on the formation of wide cold-frontal rainbands (Kawashima 2016). The Doppler radar studies include the retrieval of thermodynamic structure of Baiu (Meiyu) frontal rainband (Kawashima et al. 1995), the retrieval of latent heating profile in tropical cloud systems observed during TOGA-COARE (Ushiyama et al., 2003), the mechanism responsible for the successive development of snowbands along the coastal region of Hokuriku district in Japan (Yoshihara et al., 2004), the structure and energetics of a wavelike disturbance along a snowband (Kawashima and Fujiyoshi, 2005), and the modulation of convective activity over Sumatra Island due to the propagation of the Madden-Julian Oscillation (MJO) (Kawashima et al., 2006).
