The northeastern China cold vortex (NCCV) has an important influence on the regional rainstroms over East Asia. Using the National Centers for Environmental Prediction Final (FNL) reanalysis dataset and the Global Precipitation Measurement product, an improved objective algorithm for identifying heavy precipitation NCCV (HPCV) events from 2001 to 2019 was designed. The climatological features of 208 HPCV events were investigated. The number of HPCV events showed an upward linear trend, with the highest frequency of occurrence in summer. The most active region of HPCVs was in the Northeast China Plain of 40–55° N. Most HPCV events lasted 2–5 days and had radii ranging from 250 to 1000 km. About 79% of the HPCV events was initiated (dissipated) in the definition region (35–60° N, 115–145° E). The initial position was close to the western boundary of the definition region, and the final position was mainly in the first and the fourth quadrants. The HPCV events that moved into the study region had a longer duration than those initiating in the region. The monthly variation of the strongest precipitation in the HPCV events showed a bimodal pattern, with two peaks in June and October. The location of the strongest precipitation was mostly concentrated within 2000 km southeast of the HPCV systems and it had a strong positive correlation with the center of HPCV events.
