In
the last ten years, scientists have shown that it is possible to detect
falling snow and measure surface snowpack information from the vantage
point of space. But there remains much that is unknown about the fluffy
white stuff. A team from NASA and Environment Canada are hoping their
Global Precipitation Measurement satellite and ground mission will set
new standards and bring global measurements every three hours.

Coinciding
with a peak in solar activity, NASA Goddard Space Flight Center’s Space
Weather Laboratory will soon simultaneously produce as many as 100
computerized forecasts by calculating multiple possible parameters,
improving our ability to predict the impact of solar storms. Currently,
just one set of conditions is used to anticipate solar-storm activity.

With
an almost biblical onslaught of twisters, floods, snow, drought, heat,
and wildfire, the U.S. in 2011 has seen more weather catastrophes that
caused at least $1 billion in damage than it did in all of the 1980s,
even after the dollar figures from back then are adjusted for inflation.

Carbon
dioxide levels for 2010 have recently been release by the World
Meteorological Organization. They show that CO2
levels are now at 389 parts per million, up from about 280 parts per
million 250 years ago. Also, levels are up 2.3 parts per million from
2009.

After
meeting in Uganda, the Intergovernmental Panel on Climate Change
issued a report on global warming and extreme weather. It predicts that
heat waves that are now once-in-a-generation events will become hotter
and happen once every five years mid-century. Other extreme weather
events including storms and floods, it says, will become more frequent
and more pronounced.

A
climate report from the Intergovernmental Panel on Climate Change won’t
be released for a few weeks, but a draft of the report from a panel of
the world's top climate scientists paints a wild future for a world
already weary of weather catastrophes costing billions of dollars.

After
a years-long delay, NASA’s newest climate satellite blasted into space
early Friday on a dual mission to improve weather forecasts and monitor
climate change. Five scientific instruments will extend more than 30 key
long-term NASA datasets, including ozone layer measurements, land
cover, and ice cover.

Double rainbows are rare, but until now, sightings of triple, and even quadruple, rainbows have never been proven. A meteorologist whose perseverence recently generated photograph evidence of these compound rainbows has also provided guidelines that shows how to find them.

From monsoons in Mumbai to windstorms in Seattle, weather patterns around the world are influenced by the MJO, or Madden-Julian Oscillation, a 30- to 60-day atmospheric wave that is poorly understood. Pacific Northwest National Laboratory and the National Center for Atmospheric Research have joined forces to model MJO and better understand how tropical weather affects global climate.

The climate on the surface of Venus is consistently nasty, with searing temperatures and crushing atmospheric pressures, with no water and no relief from any change in seasons. In the upper atmosphere, however, scientists have spotted surprising signs of dynamic, changing patterns.
