Evaluating Common Characteristics of Antarctic Tropopause Polar Vortices

期刊: JOURNAL OF THE ATMOSPHERIC SCIENCES, 2023; 80 (1)

Tropopause polar vortices (TPVs) are coherent circulations that occur over polar regions and can be identified by a local minimum in potential tempera......

Random Errors in the Stable Boundary Layer: Implications for Modern Observational Techniques

期刊: JOURNAL OF THE ATMOSPHERIC SCIENCES, 2023; 80 (2)

For decades, stable boundary layer (SBL) turbulence has proven challenging to measure, parameterize, simulate, and interpret. Uncrewed aircraft system......

Underlying Microphysical Processes in the Melting Layer during Moderate Precipitation: Evidence from Ground-Based Data

期刊: JOURNAL OF THE ATMOSPHERIC SCIENCES, 2023; 80 (5)

We performed a detailed analysis of ground-based data to investigate changes in the morphological proper-ties and particle size distribution of precip......

The Onset of a Blocking Event as a Traffic Jam: Characterization with Ensemble Sensitivity Analysis

期刊: JOURNAL OF THE ATMOSPHERIC SCIENCES, 2023; 80 (7)

Recently, Nakamura and Huang proposed a theory of blocking onset based on the budget of finite-amplitude local wave activity on the midlatitude wavegu......

Seasonal Differences of Precipitation and Microphysical Characteristics over the Asian Monsoon Region Using Spaceborne Dual-Frequency Precipitation Radar
