August 02, 2013 - CHINA -
The authorities in Hangzhou city in China's Zhejiang province are taking a slightly more direct approach to tackle the heatwave sweeping the region.
They are launching cloud seeding rockets into the sky in order to make it rain and hopefully bring down the 35C temperatures, which have triggered a level two emergency from the China Meteorological Administration (CMA).
Cloud seeding is a form of intentional weather modification. By dispersing substances, in this case silver iodide, into the air by rocket or plane, scientists can attempt to change the amount of rain that falls from clouds by altering the microphysical processes within the cloud.
Clouds were seeded during the 2008 Summer Olympics in Beijing using rockets, so that there would be no rain during the opening and closing ceremonies.
However, some dispute the effectiveness of the technique. There are also concerns over the toxicity of silver iodide and its effect on the environment. - Daily Mail.
Hundreds of millions of Chinese residents are sweating out an exceptional heat wave, with major cities such as Shanghai recording new all-time record high temperatures.
Weather historian Christopher C. Burt of Weather Underground reports that Shanghai, China's largest city, has broken its all-time record high in records reaching back to 1873, reaching 105.1ºF on July 26. The misery has been compounded by brutally warm nights; the city's low July 30 only dipped to 88ºF, with the heat index dropping no lower than 99ºF.
Shanghai, where average July highs are in the mid 80s to low 90s, hit the century mark 14 different days in July, including the last nine days in a row.
The heat wave, the worst in at least 140 years in some parts, has left dozens of people dead and pushed thermometers above 40 degrees C (104 F) in at least 40 cities and counties, mostly in the south and east. Authorities for the first time have declared the heat a "level 2" weather emergency- a label normally invoked for typhoons and flooding.
"It is just hot! Like in a food steamer!" 17-year-old student Xu Sichen said outside the doors of a shopping mall in the southern financial hub of Shanghai while her friend He Jiali, also 17, complained that her mobile phone had in recent days turned into a `'grenade."
"I'm so worried that the phone will explode while I'm using it," He said.
On Tuesday, the director of the China Meteorological Administration activated a "level 2" emergency response to the persistent heat wave. This level requires around-the-clock staffing, the establishment of an emergency command center and frequent briefings.
Some Chinese in heat-stricken cities have been cooking shrimps, eggs and bacon in skillets placed directly on manhole covers or on road pavement that has in some cases heated up to 60 degrees C (140 F).
Extreme heat began hitting Shanghai and several eastern and southern provinces in early July and is expected to grip much of China through mid-August.
Burt said a swath of provinces in the east-central part of the country have taken the brunt of the prolonged heat wave, likely experiencing their warmest July in modern history. He noted the coastal city of Ningbo reached 108.9ºF on July 26 to establish the highest temperature ever recorded at a coastal location in East or Southeast Asia.
The South China Morning Post said large crowds of people thronged subway stations in several Chinese cities, seeking the air-conditioned tunnels as a relief from the extreme and prolonged heat. The newspaper's website said Changsha, the capital of Hunan, established a new record of 25 consecutive "high-temperature days," days when the mercury topped 95ºF.
Little relief is expected in this region, as triple-digit heat is likely to persist well into early August across these same areas, along with widespread lows in the 80s. - TWC.
