The initial typhoon of the year made a late visit and there were just two typhoons making landfall on the province, 1.7 typhoons less than the average, and four typhoons affected Guangdong, having little influence. The temperature was so high and the precipitation was so little that concentrated periods of heavy meteorological drought were caused. Waves of cold air were significant at both the beginning and the end of the year, decreasing temperature significantly. The number of hazy days remained at a relatively low level across the province. In 2021, the overall characteristics of the weather and climate in Guangdong can be summarized as “the temperature was high, the precipitation was little and there were few landfall-making typhoons, and meteorological droughts resulted in serious consequences for some concentrated periods of the year”. In general, the climatic prospect of Guangdong was bad in 2021.
