Abstract: The long-term change in the February precipitation and temperature and associated large-scale circulation and sea surface temperature (SST) features are examined by using the dataset from 86 surface stations for recent 59 years (1961—2019) in Guangdong. The following features are identified. The February precipitation periods during 1961—1981 and 1999—2019 were two typical rain-deficient periods with significantly different temperature in Guangdong, corresponding to'cold-dry'and'warm-dry'phase, respectively. Accompanying the afore-described precipitation and temperature changes, the general circulation and moisture transport between the two rain-deficient episodes presented opposite features. In the'cold-dry'phase (1961—1981), meridional distribution prevailed over 500 hPa geopotential height with strong East Asian Trough (EAT) and the East Asian Winter Monsoon (EAWM). In addition, under the control of the surface cold high pressure, the northward cold surge was so strong that the warm moisture air mass from sea couldn't arrive at Guangdong, the place where the moisture divergence field was; thus the precipitation was less and the temperature was lower than normal. However, in the'warm-dry'phase(1999—2019), zonal circulation pattern with weak EAT and EAWM dominated over the Asian mid- and high latitudes region. The airflow from the cold high pressure was too weak to affect Guangdong, while southerly flow was significantly stronger than normal. Meanwhile, owing to an anti-cyclonic circulation anomaly over the Qinghai-Tibet Plateau, the inactive south branch westerlies were not favorable for moisture transport to Guangdong, leading to much deficient moisture supply for precipitation and higher temperature over Guangdong in February. Further analysis shows that the SST over the tropical Eastern Pacific and central North Pacific played an important role in the precipitation anomaly between the two different stages, respectively. In the first phase, anomalous cold SST of the tropical Eastern Pacific had an influence on February precipitation owing to the weak meridional wind shear at 850hPa. However, in the second stage, anomalous warm SST of the central North Pacific influenced the monthly rainfall based on anomalous anticyclone circulation in the central North Pacific. The uniform pattern of the tropical Indian Ocean, the western Pacific warm pool area and the central North Pacific SST anomalies were external forcing factors that affect Guangdong's February temperature. The first two mainly affected the temperature in Guangdong through the circulation of the EAT during 1961—2019, while the SST in the central North Pacific only affected the temperature in Guangdong in February during the'warm-dry'period.
