Abstract: This study identifies and tracks 3730 CVs (cold vortexes) in Northeast Asia from 2000 to 2019, including “short duration” CVs lasting 6 h, 24 h) and 24 h, 48 h), as well as traditional northeast CVs lasting at least 48 h. It examines differences in the spatial and temporal distribution, intensity, and scale of CVs with different durations, along with their impact on precipitation in Northeast China during warm seasons. The results show the following: (1) CVs lasting 6 h, 24 h) are the most common, accounting for about 60%, while traditional CVs are the least common, at about 15%. (2) CVs demonstrate considerable interannual and intermonthly variations, with most occurring from May to August. However, CVs with different durations peak in different months. (3) The high occurrences of CV centers with durations of 6 h, 24 h), 24 h, 48 h), and ≥48 h appear in the northeast corner, northeast quadrant, and central part of the study region, respectively. Initial CV centers mainly occur near the western boundary between 45° and 55°N. CVs lasting 6 h, 24 h) and 24 h, 48 h) frequently emerge in the northeast quadrant and north-central part, respectively. They are typically found near the eastern boundary of the region north of 40°N. (4) CVs with longer durations exhibit stronger centers and larger sizes. They are also stronger and larger during cold seasons compared to warm seasons. (5) Under CV conditions, the average contribution of both total precipitation and short-duration heavy precipitation exceeds 60%, with the latter being significantly larger. Longer-lasting CVs correspond to higher precipitation ratios. The spatial distributions of total precipitation and short-time heavy precipitation under different CV durations present remarkable differences.
