Let It Snow For Science

Let It Snow for Science

When the weather outside is frightful…

Science in the field gets even more delightful. Two different missions are in the field right now, studying snow and how it affects communities around the country.

From our Wallops Flight Facility in Virginia, the IMPACTS mission is flying up and down the East Coast, investigating how snow forms inside clouds. In Grand Mesa, Colorado, SnowEx’s teams on the ground and in the air are taking a close look at how much water is stored in snow.

Hate going out in the storm? The IMPACTS mission can help with that! IMPACTS uses two planes – a P-3 Orion and an ER-2 – flying through and high above the clouds to study where intense bands of snowfall form. Better understanding where intense snow will fall can improve forecast models down the road — helping prepare communities for snowstorms.

Cameras mounted on the wings of the P3 took microscopic images of snowflakes, like this one.

At the same time, the SnowEx team is in Colorado, studying the depth and density of snow. Researchers are making radar spirals with snowmobiles and working in giant snow pits to measure things like snow water equivalent, or how much water is stored in snow.

SnowEx is helping us better understand snow’s role in ecosystems and human systems, like irrigation for agriculture. If you want to bring some corn for popping, SnowEx’s science can help grow that crop.

I found an old train ticket in this second hand book I bought a while ago.

I’m wondering who was so passionate about studying Romanticism on a train from Milano to Trieste on 11th april 1988. Were they returning from holidays and studying for an exam? Or were they doing research for their thesis?

Deer are considered to be the sacred messengers of Shinto deities, and are often depicted in mandalas, as seen here. A white stag rides on a cloud, symbolizing his role as a messenger between the earth and the gods. On his saddle is a branch of the sacred sakaki tree and a mirror, which, along with the sword and jewel, is one of the three sacred symbols of Shinto. “Deer Mandala,” 1600s, Japan

Hoje é o Dia Mundial da Eficiência Energética!

Nós já sabemos que economizar energia não é só uma questão de apagar as luzes quando não precisamos delas. Então, o que mais podemos fazer?

Prefira produtos locais ou regionais, pedale para chegar à escola e trabalhe para vencer a pressa ou, ainda, troque aparelhos domésticos por alternativas mais ecológicas – sim, essas pequenas mudanças podem ser de grande impacto, se todos nós as fizermos.

Tumblr, como você vai comemorar hoje? Para mais informações, clique aqui!
