A new generation of weather satellites is helping researchers gain insights into the complex relationship between the cryosphere – the planet’s cold regions – and the climate. With drinking water supplies dwindling around the world, understanding the cryosphere is becoming a front-burner issue.

Major winter storm poised to wallop U.S. Mid-Atlantic

Originally Published by EarthSky – A major winter storm is poised to wallop the U.S. Mid-Atlantic states bring large amounts of snow to cities including Baltimore, Md., Washington, D.C. area on March 2 and 3, according to NOAA’s National Weather Service. NOAA’s GOES-East satellite captured this image on March 2, 2014 of the clouds associated with the winter storm as it continued moving east toward those cities.

A joint mission between NASA and Japan’s space agency, the Global Precipitation Measurement (GPM) Core Observatory, will for the first time provide near real-time information about rain and snow around the globe.

How do snowflakes get their shape?

Originally Published by EarthSky – The shape of snowflakes is influenced by the temperature and humidity of the atmosphere. Snowflakes form in the atmosphere when cold water droplets freeze onto dust particles. Depending on the temperature and humidity of the air where the snowflakes form, the resulting ice crystals will grow into a myriad of different shapes.

Amplified Fire Occurrences in Response to Drought and Vegetation Stress in the Western Ghats of India

Location of the study area in India.

This study demonstrates the importance of the intensity and severity of drought in contributing to anomalous fire events, an important driver of global fire regimes. While spatial and temporal analysis of fires’ response to droughts indicates the vulnerability of all land cover types, the primary wet evergreen and secondary moist deciduous forests are particularly at risk.
