NASA Researchers Explore Lightning's NOx-ious Impact On Pollution, Climate Greenbelt MD (SPX) Oct 28, 2009 
Every year, scientists learn something new about the inner workings of lightning. With satellites, they have discovered that more than 1.2 billion lightning flashes occur around the world every year. (Rwanda has the most flashes per square kilometer, while flashes are rare in polar regions.) Laboratory and field experiments have revealed that the core of some lightning bolts reaches 30,000 ... read moreMajor dust storm blankets eastern Australia 
Sydney (AFP) Sept 23, 2009The worst dust storm in decades swept across eastern Australia on Wednesday, blanketing Sydney and snarling transport as freak conditions also brought earthquakes, giant hailstones and even a tornado. Gale-force winds dumped thousands of tonnes of red desert dust on Australia's biggest city, shrouding it in an eerie orange haze and coating the iconic Sydney Opera House in a fine layer of ... more

Lightning kills three women in DR Congo
Kinshasa (AFP) Sept 22, 2009Separate lightning strikes killed three women in the same region of the Democratic Republic of Congo, after torrential rains began, a local chief said Tuesday. A 26-year-old cook at a convent in the Tshimbulu district died in hospital after being struck by lightning on Friday, chief Laudes Nkashama told AFP. A second woman was killed at her home in Tshidimba, five kilometres from Tshimbu ... more Dust, quakes and fire as Australia reels from wild weather 
Sydney (AFP) Sept 23, 2009Australia's biggest city was shrouded in an eerie blanket of red dust on Wednesday as bushfires, earthquakes, wild winds and massive hail stones caused havoc in the country. Sydney's cars and buildings turned orange as strong winds blew desert dust across the city, snarling commuter and air transport and prompting a warning for children and the elderly to stay indoors. Residents wore ... more Cameroon lightning strike kills five schoolchildren 
Yaounde (AFP) Sept 16, 2009Lightning killed five schoolchildren when it ripped through a classroom in northwestern Cameroon and caused around 50 others to be treated in hospital for trauma, authorities said Wednesday. The children were killed instantly when a bolt of lightning flashed through their classroom on Monday, North West Region governor Abakar Ahamat told AFP. Around 50 other children were traumatised by ... more Urban Sprawl, Wet Falls And Winter Affect Severe Weather 
West Lafayette IN (SPX) Sep 15, 2009Previously rare big city storms - like a tornado Aug. 19 that downed trees and ripped off roofs in downtown Minneapolis and the powerful thunderstorms in New York City a day earlier - may not be so unusual anymore. As large urban areas continue to expand, they appear to influence tornadoes and other severe weather, research suggests. Cities could be even more at risk if located in a ... more |

Australia sweats through long, hot winter
Sydney (AFP) Aug 27, 2009Drought-hit Australia endured an exceptionally hot winter, with abnormal temperatures shattering records that had in some places stood since World War II, official figures show. In a special climate statement released late Wednesday, the weather bureau said maximum temperatures in August were broadly three degrees Celsius (37 degrees Fahrenheit) higher than the long-term average. "August ... more Lightning's Mirror Image ... Only Much Bigger 
Washington DC (SPX) Aug 28, 2009With a very lucky shot, scientists have captured a one-second image and the electrical fingerprint of huge lightning that flowed 40 miles upward from the top of a storm. These rarely seen, highly charged meteorological events are known as gigantic jets, and they flash up to the lower levels of space, or ionosphere. While they don't occur every time there is lightning, they are ... more August Heat 
Washington DC (SPX) Aug 26, 2009If you are wilting under the summer heat, consider this: your child may one day think of summer 2009 as "back in the cool old days." To illustrate expected increases in extreme summer heat, scientists at Climate Central have analyzed climate change projections made with global climate models. Scientific literature based on these models anticipates much more frequent occurrences of hot days ... more Heavier Rainstorms Ahead 
Cambridge MA (SPX) Aug 21, 2009Heavier rainstorms lie in our future. That's the clear conclusion of a new MIT and Caltech study on the impact that global climate change will have on precipitation patterns. But the increase in extreme downpours is not uniformly spread around the world, the analysis shows. While the pattern is clear and consistent outside of the tropics, climate models give conflicting results within the ... more |
