This is a project I've been working on for a while....it is an aligned sequence of images of Hurricane Dean in the Atlantic/Caribbean basin from 0000 UTC August 18, 2007 to 0900 UTC August 21, 2007. During this time, Hurricane Dean was a strong Category 4/5 storm.

The images are aligned such that the outer rain bands have minimal displacement (semi-rotating coordinate frame). The black dot in the middle of the image is the eye of the hurricane.

[EDIT: These were taken using IR (Channel 4) from the GOES12 satellite. The images have been contrast-enhanced to bring out detail in the cloud structure.]

Spin-O-Vision of the core of Hurricane Dean:

(Click to launch GIF)

Same image and source info as above, this time using a rotating coordinate frame (ca. 45 degrees counterclockwise/3 h, then adjusted to alignment) to freeze out the motion of the central core of the hurricane.

From this (rotating) viewpoint, the outer rain bands can be seen to precess outwards clockwise.

Some tweaking of contrast levels to bring out detail in the rain bands. (Cropping also done to prevent seasickness.)

Spin-O-Vision of the outer fringes of Hurricane Dean:

Attached Image

(click to launch GIF)

Rotating coordinate frame (5 degrees counterclockwise/3 h) to freeze out the motion of outer rain bands of the hurricane. The inner core spins much faster (45 degrees/3 h) and can be seen to provide impulsing shocks that create waves propagating outwards in the hurricanes outer edges.

Some tweaking of contrast levels to bring out detail in the rain bands.

Animated zoom of the lower left section of the sequence above:

(click to launch GIF)

With a 5 degree/3 h counterclockwise rotating coordinate frame to lock the outer band motion, the rhythmic wavelike nature (almost standing waves) of the outer rain band pulsations can be seen.

A stunning image from the ISS taken of Hurricane Ike approaching the Texas coast:

The wave-like nature compares to the Hurricane Dean sequence above.

Aquavision image of Tropical Storm Erika in her final gasps:

Attached Image


Outflow band of whitish-blue cirrus can be seen. Combination of IR2, IR4, and WV band images gaken by GOES-E on September 2, 2009 at 1800 UTC.

For scale, the Great Lakes can be seen at upper left of the image.

Here is a time-lapse 4 minute video prepared by NOAA using orbital IR imagery for the entire 2008 North Atlantic hurricane season.

(It is mesmerizing to watch, almost like the flames in a fire. The diurnal build up of thunderstorms creates a rhythmic pulsing pattern. Neat to see how a strong cold front sweeping across North America shuts down the diurnal effect.)

Just stumbled on this old thread -- here are some nice images of Hurricane Wilma from the ISS. Wilma was briefly the strongest hurricane every recorded -- the eye is just amazing.

The pictures are cool! Storms are stunning to look when viewed from distant, but destructive.
