Awe-filled learning unfolds as a kindergarten class, accompanied by educators, investigates snow and water with tools, toboggans and more.
Snowpack protects tree roots and soil from harmful freeze/thaw cycles.
Climate change is shrinking winter snow cover in Northeast forests, which protects tree roots and soil from repeated freezing and thawing. This could stunt tree growth and forest carbon storage.
Technology can only go so far in making sense of our vast and intricate atmosphere.

The storm intensified rapidly off the US east coast.
The US was hit by a 'bomb cyclone' last week, bringing icy cold and driving snow. These storms develop very rapidly, forming outside the tropics, typically on continental east coasts in winter.

Moaning about weather forecasts is almost an Australian national pastime. But weather predictions have improved a lot, and with a new satellite and supercomputer, they are about to get even more reliable.
Future snows will mostly happen in big falls.
This weekend is predicted to be the coldest of the year in Australia. But it has otherwise been a slow start to the snow season, and my research shows that this is a sign of things to come.
Sometimes you don’t need a measuring stick to come up with an assessment: really, really deep.
It's really hard to measure snowfall accurately. The National Weather Service relies on more than 8,000 volunteers with rulers.
