China's northeastern provinces of Jilin and Liaoning artificially induced rain on Thursday, offering temporary relief from a severe drought that has lasted almost a month.

Four planes and 78 rocket systems were used to seed clouds and produce 283 million tons of rain in more than eight hours across Liaoning. At least 14 areas received more than 20 mm of rain by noon, according to the provincial meteorological bureau.

The operation was started late on Wednesday, right after rain started to pelt the thirsty province.

Another large rainmaking operation is scheduled on Saturday, when a second precipitation is expected to arrive, said Chen Yanqiu, deputy head of the bureau.

Almost 1.6 million people and 750,000 head of livestock in 14 cities, 89 counties and 914 townships are suffering water shortages. About 2.05 million hectares, or 49 percent of the province's crops, were affected by drought, the worst in 56 years.

In neighboring Jilin, 140 million tons of rainfall were artificially induced on Thursday.

However, the effort failed in some of the worst-hit areas where the rain vaporized before it reached the ground, said Jin Dezhen, director in charge of the rainmaking program.

People in Jilin have been fighting the worst drought in history since early June.

Water supplies had resumed to more than 150,000 rural people and 210,000 head of livestock by Wednesday, leaving 470,000 people and 400,000 head of livestock short of drinking water before the rainmaking effort. Almost 78 percent of crops in the province were affected.

The local government has allocated 370 million yuan (US$48.6 million) to the drought-relief campaign.
