Distinct Characteristics of Convectively Induced Turbulence (CIT) and Non‐CIT in the Western Pacific Using In Situ Aircraft Data and GK‐2A Satellite Data

Abstract This study introduces a newly defined turbulence patch that includes continuous turbulence reports of in situ aircraft data, separating at least 5‐min from others. This enables the individual turbulence patch to be characterized more easily by their possible sources than by an isolated data point. Using 5 years of satellite observations, we classified new turbulence patches into convectively induced turbulence (CIT) and non‐CIT. We also classified patches into long‐ and short‐duration events. Patch duration shows clear latitudinal differences, especially for CIT. CIT duration is linked to the size of underlying convective systems and strength of background winds. Signal analysis shows that CIT in low latitude exhibits a high skewness and kurtosis, indicating highly variable turbulence with occasional extreme fluctuations. Meanwhile, long‐duration non‐CIT patches occur frequently under enhanced Clear‐Air‐Turbulence (CAT) diagnostics, indicating an association between CAT‐prone conditions and encounter duration. These findings support turbulence risk assessment and nowcasting.
