With statistical and wavelet analysis, snowfall data in recent 41a and SST of November in recent 25a are analyzed for cold airflow snowfall in Shandong Pe ninsula in winter. The results show that snow distribution has close relation to the landform with more snowfall in the northeast peninsula and less snowfall in the other areas. Cold airflow snowstorms are of remarkable mesoscale character and often occur in December. By using wavelet analysis it is also found that t he main period is about 4, 7 and 17 years. The statistical analysis shows that S ST of Bohai sea in November is remarkably useful signal for cold airflow snowfa ll prediction in winter.
