NASA's AIM spacecraft is discovering unexpected "teleconnections" in Earth's atmosphere that link weather and climate across vast distances.Teleconnection in atmospheric science refers to climate anomalies being related to each other at large d
The season of noctilucent, "night-shining", clouds has begun in the southern hemisphere and NASA's AIM spacecraft is monitoring a vast bank of rippling electric-blue NLCs blanketing almost all of Antarctica.
Noctilucent clouds
Polar mesospheric clouds—also known as noctilucent or “night shining” clouds—form between 76 to 85 kilometers (47 to 53 miles) above the Earth’s surface, near the boundary of the mesosphere and thermosphere, a region known as the…
Noctilucent clouds (NLCs) turn on every year in late spring, reaching almost full intensity over a period of no more than 5 to 10 days. These electric-blue ice clouds hang 85 km (53 miles ) above Earth’s surface, at the edge of space itself, circling the north and
