“天河一号”是我国首台千万亿次超级计算机,曾在2010年全球超级计算机排行榜上位列第一。如今,它正“紧盯”雾霾,为河北廊坊和保定市的市民服务呢!预报雾霾看起来和预报天气差不多,难度却大很多。天气预报通常只关注“温、湿、风、压”4个预报量,而雾霾预报涉及70个预报量,计算量是天气预报的5倍。且我国城市内许多地方差别很大,雾霾预报分辨率有时为2至3千米,这也大大增加了计算量。
“Tianhe One ” is China’s first petaflop supercomputer, which ranked first in the 2010 global supercomputer rankings. Nowadays, it is “staring at” the smog and serving the residents of Langfang and Baoding in Hebei Province. Forecasting the smog It looks like the weather forecast is similar but the difficulty is much greater. Generally, the weather forecast only focuses on the four forecasts of “temperature, humidity, wind and pressure”, while the forecast of haze includes 70 forecasts and the calculation amount is five times of the weather forecast. And many places in our country vary greatly, and the resolution of haze prediction is sometimes 2 to 3 km, which also greatly increases the amount of calculation.
