People in Kunming has been attracted by solar halo from 12:30 to 14 o’clock on March 25.  

"I gess it will rain. Farmers usually say that if the nimbus is close to the sun, it will rain soon. If not, the rain may delay for a few days,"said Zhang, a resident who was attracted by the icebow.

" Halo is an optical phenomenon produced by ice crystals creating colored or white arcs and spots in the sky. Many are near the sun. Light is reflected and refracted by the ice crystals and water droplets, and may split up into colors because of dispersion."said Pu Guiming(普贵明), a correspondent in Yunnan Provincial Weather Bureau. Pu also said the halo is affected by red tide, and the moisture in the upper air increases, which is an empirical means of weather changes in the coming two days.

It is forecast that it may see shower or thunder shower in northern areas of central Yunnan in the coming two days. It may be sunny, partly cloudy, in most areas of Yunnan from March 28 to 30.
