Short Summary

This study investigates the temporal and spatial characteristics of convective initiation (CI) over the Tibetan Plateau during the warm season using FengYun-4A satellite data. It reveals that CI predominantly occurs on windward slopes, linked to monsoon activity, and exhibits distinct diurnal and day-night spatial patterns.

Objective

• To investigate the temporal and spatial distribution characteristics of convective initiation (CI) during the warm season over the Tibetan Plateau (TP).

Study Configuration

• Spatial Scale: Tibetan Plateau (TP), with a high-frequency area identified at 27° N–30° N, 87° E–92° E.
• Temporal Scale: Warm season, from 2018 to 2022.

Methodology and Data

• Models used: None explicitly mentioned.
• Data sources: Observation data from the FengYun-4A (FY-4A) satellite.

Main Results

• Convective initiation (CI) mainly occurs on the windward slopes of valley plains along mountain ranges over the Tibetan Plateau during the warm season.
• A high-frequency area for CI is located at 27° N–30° N, 87° E–92° E.
• CI occurrences are closely linked to monsoon activity, intensifying with the onset of the monsoon and expanding northward during summer.
• CI exhibits a single diurnal peak at 13:00 local solar time and a minimum at 23:00 local solar time.
• Daytime CI primarily occurs over the plains, while nighttime initiation is mainly concentrated along the hillsides.

Contributions

• Provides a deeper understanding of the characteristics of convective initiation over the Tibetan Plateau during the warm season.
• Offers insights into the temporal and spatial distribution patterns of CI, including its link to monsoon activity and diurnal variations.
