Satellite Image Of Snow On North China Plain

How lightly it has been snowing on the drought-afflicted North China Plain is shown by this satellite image taken in the early afternoon of Feb. 14th by the China Meteorological Administration‘s FY3B’s meteorological satellite. Snow cover is indicated by the areas in blue.

The plain only got its first snowfalls of the season this month, a light dusting despite extensive cloud-seeding. No more rain or snow is in the forecast for the next few days. The drought continues unalleviated. Vice Premier Hui Liangyu, at the end of a three day visit to Shanxi, called for preparations for a long-term fight against drought.

Update: Peversely, barely 750 miles away the east coast of the Korean peninsula has had days of record snowfalls, with rescue helicopters being needed to drop food to cut-off villages.

Tangjiashan Flood Alert Lifted And Latest Satellite Images

The outflow from the Tangjiashan quake lake has slowed to 56 cu. meters a second and the water level has dropped nearly 30 meters from its peak, officials said Wednesday. They have also lifted the flood alert as fears of downstream flooding receded. At those outflow rates the lake is likely to fill up a bit again, though the sluicing operation will keep the level at around 20 meters below the peak.

NASA satellite images (pdf), snapshots below, show the Jiangjiang River downstream from the quake lake before and after the sluicing. The top image, taken on June 8th, shows the river slow-moving and hampered by landslides. The lower image, taken on June 10th, shows the river as a torrent, submerging land along its banks, and flooding over the landslide that was previously visible in the upper picture. Its color indicates that it carries considerable sediment, including sediment from the breached landslide upstream.
