正文(英文) | June 2020 was just 0.01°C below the record-breaking temperatures of June 2019, with exceptional heat in Arctic Siberia, according to the Copernicus Climate Change Service (C3S). Globally, temperatures last month were 0.53°C warmer than the average June from 1981-2010. Over Arctic Siberia, average temperatures reached as high as 10 °C above normal for June, fuelling severe wildfires. During both June and for the last 12 months, Siberia stands out as the region with the largest anomalies. This culminated in a temperature of 38°C on 20 June at the Verkhoyansk observing station, according to the Russian Federal Service for Hydrometeorological and Environmental Monitoring (Roshydromet). WMO will now verify whether this is a new record temperature north of the Arctic Circle.
Data from C3S, which is implemented by the European Centre for Medium Range Weather Forecast (ECMWF), further indicate that snow cover and surface soil moisture reached record lows for June over the Siberian Arctic in June 2020. These are also factors, which likely played a role in the unusually high temperatures reached in the region. The lower-than-usual soil moisture is believed to have been a contributing factor to increased fire activity, mostly concentrated in the far north-east of Siberia. Scientists from the Copernicus Atmosphere Monitoring Service (CAMS), also implemented by ECMWF, have been monitoring wildfire activity since the start of the boreal fire season in early May.
According to the monthly climate report, Europe saw temperatures that were far above average in the north and below average in the south. Temperatures were predominantly higher than average over land, particularly over the central USA and southern Canada, north-eastern Canada, and most of Africa, the Middle East, China, South America and Australia. Elsewhere, Antarctica exhibited characteristic wintertime geographical variability where temperatures were quite substantially above or below average. Northern India saw temperatures that were distinctly below average.
