New insights into what triggers lightning

May 8, 2013

0

Cosmic rays interacting with water droplets within thunderclouds could play an important role in initiating lightning strikes. That is the claim of researchers in Russia, who have studied the radio signals emitted during thousands of lightning strikes. The work could provide new insights into how and why lightning occurs in the first place. Although most […]

Satellites, balloon-borne instruments and ground-based devices make 30 million observations of the atmosphere each day. Yet these measurements still give an incomplete picture of the complex interactions within Earth’s atmosphere. Enter climate models. Through mathematical experiments, modelers can move Earth forward or backward in time to create a dynamic portrait of the planet. NASA Goddard’s […]

Global warming ‘confirmed’ by independent study

October 21, 2011

The Earth’s surface really is getting warmer, a new analysis by a US scientific group set up in the wake of the “Climategate” affair has concluded. The Berkeley Earth Project has used new methods and some new data, but finds the same warming trend seen by groups such as the UK Met Office and Nasa. The project […]

The Ozone Hole: Summer 2011

NASA, NOAA Data Show Significant Antarctic Ozone Hole Remains The Antarctic ozone hole, which yawns wide every Southern Hemisphere spring, reached its annual peak on Sept. 12. It stretched to 10.05 million square miles, the ninth largest ozone hole on record. Above the South Pole, the ozone hole reached its deepest point of the season […]

The real Greek tragedy may be the climate

David Strahan Greece’s debt crisis threatens more than the collapse of the euro and the European Union – it would also be a climate disaster GREECE is going to default, one way or another, that much is clear. The bigger question is whether it will also leave the euro and what that would mean. What […]

Moon’s shadow creates a wake

October 12, 2011

During a total solar eclipse the Moon comes directly between the Sun and the Earth, casting a dark shadow that moves across land and sea. Now, researchers in Taiwan and Japan have shown that this shadow creates a pocket of high-pressure air that cuts through the atmosphere much like a boat through water – leaving […]

What’s the weather like on other planets?

September 7, 2011

Mercury he baby of the Solar system and closest to the Sun, smallest-planet Mercury has no atmosphere, so its weather forecast is usually fairly dull. However, visitors would be advised to either wrap up very warm, or slap on lots of SPF 50, depending on which part of the planet they stop off at – […]

Firing laser beams into the sky could make it rain, say scientists

August 30, 2011

Water droplets have been created by shooting lasers into the air. The technique might be used to create or prevent rain Ever since ancient farmers called on the gods to send rain to save their harvests, humans have longed to have the weather at their command. That dream has now received a boost after researchers used a […]
