World weather news, April 2016
- Blistering heat is common across India ahead of the yearly monsoon rains; however, temperatures are soaring earlier than normal this year. Intense heat has affected the country, with impacts being felt from Hyderabad to Kolkata and New Delhi. The heat has already claimed the lives of more than 160 people and has also forced the closure of schools in Orissa until at least April 26.
- In recent weeks all-time national heat records have been observed in Cambodia, Laos, and
(almost) in Thailand, Malaysia, Singapore, and Vietnam. Meanwhile extreme heat has resulted in all-
time record high temperatures in the Maldives, India, China, and portions of Africa as well. Here
are some details:
- Cambodia: National all-time record high of 42.6C set at Preah Vihea on April 15th. This surpassed the record set just two days previously at Bantey Ampil (42.2C on April 13th). Prior to this year, the maximum measured temperature in Cambodia was 41.4C at Stoeng Treng in 1960.
- Laos: National all-time record high of 42.3C set at Seno on April 13th. This surpassed the former record of 42.0C recorded at Savannakhet in March 1933. An all-time national record high minimum temperature was measured at Takhek on April 13th of 30.5C.
- Malaysia: Near national record of 39.2C measured at Batu Embun on April 10th (the hottest temperature ever measured in central Malaysia). The all-time Malaysian record is 40.1C at Chuping on April 9, 1998. In March this year Chuping reached 39.5C.
- Singapore: Near national record set in Singapore with a 36.6C at Pulau on April 13th. National record is 37.0C at Tengah on April 17, 1983.
- All-time national temperature records have also been set for the Maldives Islands, India, China and in Africa. China's southernmost province of Hainan (Island) saw several sites breaking all-time heat records with the warmest being Danxian with a 40.5C reading on April 16th. In India on April 24th the city of Titlagarh measured 48.5C. This is the highest reliably measured temperature in India for the month of April. In addition, Bangalore recorded its all-time highest temperature on record with a 39.2C reading beating out its previous record of 38.9C observed on May 22, 1931. In the Maldives a national record high of 34.9C was observed at Hanimadhoo on April 16th edging out the previous record of 34.8C set at Kadhdhoo on March 27, 1999. In Africa Burkina Faso set its all- time national record high with 47.5C on April 13th; the previous record was 47.2C at the same site on May 13, 1984.
- With the official end of the Australian tropical season only days away, the calmest season in decades will come to an end. The season, which officially runs from 1 November through 30 April, has seen only three named cyclones originating within the Australian Tropical Basin. Having only three named storms of Category 1 strength or higher in the basin would be the fewest dating back to 1970, according to the Australian Bureau of Meteorology (BOM). According to Senior Meteorologist Jason Nicholls, "El Niņo played an important role in the low activity of the tropical season as tropical development flourished closer to Fiji and Vanuatu and away from Australia." El Niņo occurs when ocean water temperatures rise above normal across the central and eastern Pacific, near the equator which influences global weather patterns. Nicholls added, "A positive Indian Ocean Dipole during the early season limited development near Western Australia." The Indian Ocean Dipole is a measure of heat across the Indian Ocean from west to east. A positive event occurs with cooler-than-normal waters near and northwest of Australia. As a result, the first landfall did not occur in Australia until late January. Tropical Cyclones Stan, Uriah and Tatiana each strengthened to Category 2 tropical cyclone strength on the BOM scale, which means peak winds ranged between 88 and 142 km/h.
- Thailand is currently experiencing its longest heatwave in at least 65 years and authorities have advised people to stay indoors. The average temperature has risen above 40C in many regions in April, with the mercury spiking one day to a near record breaking 44.3C. The hottest day ever recorded in Thailand was 44.4C on April 27, 1960, in the northern province of Uttaradit. According to the Thai Meteorological Department, the average temperature nationwide has surpassed alert levels and the heatwave is expected to continue,
