Secondary eyewall formation in upper- and lower-layer vertical wind shear simulated in idealized tropical cyclones

About 80% of intense tropical cyclones (TCs) possess concentric eyewalls—namely, the primary and secondary eyewalls. The intensity of the TC can vary considerably during secondary eyewall formation (SEF) and eyewall replacement, posing a great chal.....»»

Study challenges classical view of the Antarctic Circumpolar Current origin and warns of its vulnerability

The Circumpolar Current works as a regulator of the planet's climate. Its origins were thought to have caused the formation of the permanent ice in Antarctica about 34 million years ago. Now, a study led by the University of Barcelona, the Instituto.....»»
