Miêu tảSouth Island blizzard 2003.jpg	This satellite image shows the aftermath of a severe blizzard that hit the South Island of New Zealand in July 2003. Higher regions are draped in snow, clearly delineating the escarpment northwest of the Southern Alps, formed by the 600 km (370 mi) long Alpine Fault.

Blizzard in New Zealand

As the clouds broke over South Island, New Zealand, on July 11, 2003, clear skies revealed the blanket of snow that remained from what is being reported as the worst blizzard to hit the country in 50 years. The bright white snow contrasts sharply with the deep green vegetation of the coastal areas as well as with the bright blue, glacier-fed lakes scattered across the Southern Alps, which run diagonally across the island. The blizzard stranded hundreds of motorists and isolated more than 400 skiers at a mountain resort. In places, the storm brought ice and freezing rain, making roads especially treacherous and bringing down trees and power lines.

This image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite. The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at MODIS’ maximum spatial resolution of 250 meters.
