Swirling Around the Eye of Hurricane Irma
Explanation: Why does a hurricane have an eye at its center? No one is yet sure.
What happens in and around a hurricane's eye is well documented, though. Warm air rises around the eye's edges, cools, swirls, and spreads out over the large storm, sinking primarily at the far edges. Inside the
low-pressure eye, air also sinks and warms -- which causes
evaporation, calm, and clearing -- sunlight might even stream through. Just at the
eye's edge is a
towering eyewall, the area of the highest winds. It is particularly dangerous to go outside when the
tranquil eye passes over because you are soon to experience, again,
the storm's violent eyewall.
Featured is one of the most
dramatic videos yet taken of an eye and rotating eyewall. The
time-lapse video was taken from space by NASA's
GOES-16 satellite last week over one of the
most powerful tropical cyclones in recorded history:
Hurricane Irma. Hurricanes can be
extremely dangerous and their perils are
not confined to the storm's center.
