Early-season heat records obliterated in China

Early-season heat records obliterated in China

Beijing just broke its February maximum temperature record by over 5ºC as a wave of exceptional early-season warmth sweeps across China.

Just days after an Arctic outbreak froze pipes and roads across the United States, China and surrounding countries are now enduring a pulse of unrivalled early-season heat.

A strong jet stream positioned above Asia is separating extremely cold air over Russia from much warmer air over China.

Prior to this year, Beijing's highest February temperature on record was 19.8ºC. On Saturday, the city broke this with a top temperature of 20.8ºC.

However this new record only lasted one day, with the city soaring to 25.6ºC on Sunday.

The weekend's heat was mind-blowing for this time of year.

Beijing's average maximum temperature during February (a winter month) is only 4ºC, based on the 30-year period from 1961-1990. This makes Sunday's top of 25.6ºC a staggering 21.6ºC above average for this time of year.

It's also nearly one month earlier than the previous earliest 25ºC of the season in Beijing. According to climate statistician and Guinness World Records consultant Maximiliano Herrera, the previous earliest 25ºC day in Beijing was on March 18, 2009.

According to Herrara, South Korea also set a new national February maximum temperature record on Sunday, when Pohang reached 24.9ºC. This beat 24.5ºC from the Jeju region in 2004.
