抄録

<jats:p>The relationships between cloud hydrometeors and convective/moist vorticity vectors are investigated using hourly data from a three‐dimensional, 5‐day cloud‐resolving model (CRM) simulation during the Tropical Rainfall Measuring Mission (TRMM) Kwajalein Experiment (KWAJEX). Vertical components of convective and moist vorticity vectors are highly correlated with cloud hydrometeors. The vertical components represent the interaction between horizontal vorticity and horizontal moist potential temperature/specific humidity gradient. The vertical components of convective and moist vorticity vectors can be used to study tropical oceanic convection in both two‐dimensional and three‐dimensional frameworks.</jats:p>
