Record high temperatures grip much of the globe, more hot weather to come – Heatwaves have arrived unusually early in 2017
20 June 2017 (United Nations) – Extremely high May and June temperatures have broken records in parts of Europe, the Middle East, North Africa and the United States, the United Nations weather agency reported today, warning of more heatwaves to come.The heatwaves have arrived unusually early, the World Meteorological Organization (WMO) said, noting at the same time that average global surface temperatures over land and sea are the second highest on record for the first five months of 2017, according to analyses by the US National Oceanic and Atmospheric Administration (NOAA).
Raging wildfires in Portugal
In Portugal, extremely high temperatures of around 40 degrees Celsius contributed to the severity of the devastating, fast-moving weekend wildfires that ripped through the country’s forested Pedrógão Grande region, some 150 kilometres (95 miles) north-east of Lisbon, leaving dozens dead and more injured.WMO reported that Portugal is not the only European country experiencing the effects of the extreme weather, as neighbouring Spain – which had its warmest spring in over 50 years – and France, have seen record-breaking temperatures. France is expected to continue see afternoon temperatures more than 10 degrees above the average for this time of year.
Plane traffic halted in southwestern US
On the other side of the Atlantic, the US is also experiencing record or near-record heat. In parts of the desert southwest and into California, temperatures have hovered near a blistering 120 degrees Fahrenheit (49 degrees Celsius). Media reports suggested today that some plane traffic was halted in and out of Phoenix Sky Harbour International Airport in Arizona because it was too hot to fly.The flight cancellations came amidst of one of the hottest days in the past 30 years of record keeping in the US state.Death Valley National Park in California issued warnings to visitors to expect high temperatures ranging from 100 to over 120 degrees Fahrenheit (38 to over 49 degrees Celsius), WMO added.WMO will set up an international committee of experts to verify the temperature and assess whether it equals a reported 54 degrees Celsius recorded in Kuwait last July, what was then the highest temperature for Asia, as well as for the entire Eastern hemisphere.
Record high temperatures grip much of the globe, more hot weather to come – UN agency
20 June 2017 (WMO) – Parts of Europe, the Middle East, North Africa and the United States of America have seen extremely high May and June temperatures, with a number of records broken. The heatwaves are unusually early and are occurring as the Earth experiences another exceptionally warm year.Average global surface temperatures over land and sea were the second highest on record for the first five months of 2017, according to analyses by NOAA, NASA-Goddard Institute for Space Studies and the European Centre for Medium Range Weather Forecasting Copernicus Climate Change Service.Only 2016 saw higher global temperatures due to a combination of a very powerful El Niño event, which has a warming impact, and long-term climate change caused by greenhouse gas emissions. So far in 2017 there has been no El Niño event.Climate change scenarios predict that heatwaves will become more intense, more frequent and longer. It is also expected that the number of hot days will continue to rise.
Europe
The Deutscher Wetterdienst (DWD), which acts as WMO’s Regional Climate Centre for Europe’s Node on Climate Monitoring, has issued a Climate Watch Advisory valid until at least 25 June. It states that a period with significantly above-normal temperatures and heat waves is expected for most parts of western Mediterranean (from Portugal to western Balkans).National meteorological and hydrological services are issuing regular forecasts, heat-health advice, as well as information on air quality, UV levels and wildfire risk.The heatwave originated as a result of very hot air moving up from the Sahara to the Iberian Peninsula and parts of the Mediterranean.
Iberian Peninsula
Extremely high temperatures of around 40°C contributed to the severity of the disastrous wildfire in Portugal which has claimed dozens of lives.An amber alert for heat – the second highest warning level – continues to be in place in the area on 20 June.The Portuguese national meteorological service, IPMA, said that over the weekend, when the fire broke out, more than one third of its weather stations measured temperatures over 40°C. The meteorological service said that for 20 June, 5 municipalities are at maximum fire risk and 58 at very high risk.
Spain
Spring 2017 (from 1 March to 31 May 2017) has been extremely warm, with an average temperature of 15.4 ° C, which is 1.7 ° C above the average of this term (reference period 1981-2010). It has been the warmest spring since 1965, having exceeded by 0.06 ° C the previous highest value, which corresponded to the spring of 2011. It has therefore been also the warmest spring since the beginning of the 21st century.The marked contrast observed between the maximum temperature anomalies, which were on average 2.5 º C above the normal value of the term, and those of the minimum temperatures, which were only 0.9 ºC higher than the normal ones.
May was extremely warm, with a temperature that surpassed the normal value by 2.4 ° C. As of June, the average temperature is well above normal values.A number of places broke temperature records for June for both maximum daytime temperatures and minimum overnight ones.These include Granada airport, 41.5°C, Madrid Retiro 40.3°C and Madrid airport 40.1°C on 17 June. The peak if the minimum temperatures was on the 19th June, when Salamanca and Zamora had record overnight temperatures of 22.1°C and 23.7°C.AEMET also reported extreme fire hazard for parts of the country on 20 June.France
Fifty one departments in France have an amber alert for high temperatures on 20 June, according to Meteo France. Temperatures for Monday included 38°C for Bordeaux, 36°C forLimoges, 34°C for Mulhouse and 33°C for Paris, Toulouse, Brest and Lille, according to Meteo France. A number of stations broke June records, including Cuers at 37.6°C and Toulon 35.3°C. Records for minimum night-time temperatures were also beaten (25.1°C in Montpellier, 25°C in Marseille) on Friday 16 June. Meteo France said that very high temperatures will continue until Friday 23 June, with temperatures between 32 °C and 38 °C in the afternoon, or more than 10°C above the average for this time of year. Other parts of Europe Many other parts of Europe, including the United Kingdom, also witnessed above average temperatures into the low to mid 30°s.
USA
