Wuhan has a subtropical monsoon (humid) climate, which is characterized by abundant annual rainfall, sufficient heat, rain and heat in the same season, light and heat in the same season, and Leng Xia is hot in winter with four distinct seasons.

The annual average temperature in Wuhan is 15.8℃- 17.5℃, the extreme maximum temperature is 41.3℃ (1934 August 10), and the extreme minimum temperature is-18./kloc.

The frost-free period of the whole year is generally 2 1 1-272 days, the total sunshine hours are 18 10 hour100 hour, and the annual total radiation is 104 kcal/cm2-/kloc-.

Extended data:

In the past 1 10 years, the annual average temperature in Wuhan has experienced decades of fluctuations of "warm-cold-warm":

1906- 1946 and 1994-20 15 are relatively warm periods, the former is equivalent to 197 1-20 10, and the latter is/.

1947- 1993 is relatively cold, which is about 0.28℃ lower than 197 1-20 10.

On the time scale of several decades, the annual average temperature in Wuhan has obviously increased and decreased.

On the 30-year scale, the maximum temperature increase rate and cooling rate appeared in 1980-2009 and 1928- 1957 respectively, and the change rates were 2.67 0.48℃/30a and-1.23 0.48 respectively.

The fastest 50 years of temperature increase and temperature decrease occurred in 1960-2009 and 1925- 1974, with the change rates of 2.20 0.50℃/50a and-1.4 0.35℃/50a, respectively.

On the scale of 20 years, the annual average temperature in Wuhan changed from cold to warm in 1920 and 1997, and changed from warm to cold in 1947.

On the scale of 30 years, 192 1 and 1994 changed from cold to warm, and since 1942, the temperature in Wuhan has obviously changed from warm to cold.

Compared with the global/northern hemisphere and China, the annual average temperature in Wuhan is basically the same, but the range is slightly larger. The stagnation of global warming is also reflected in Wuhan.

On the scale of 30 years and 50 years, the annual average temperature change rate in Wuhan began to turn in 2009; The annual scale change rate of 15 changed from positive to negative from 1997.
