Nearly caught by a severe storm!


MERIS satellite image showing the storm

On the way back, our crew members had to deviate from their programmed route because of a storm. Since Envisat's MERIS visible-infrared sensor was programmed to capture this part of the expedition as well, we got a perfect image of the storm. But of course little of the sea surface can be seen under these meteorological conditions.

Please look at the image. You can imagine the circling movement of the hurricane-like low pressure. We are in the southern hemisphere and the cyclonic movement is different from that in the north.

To compare the sense of rotation in both hemispheres, open a Meteosat image of that very day (METEOSAT_60E_03112718WV.jpg) ), positioned over the Equator at 60 degrees East.

Look for low pressure zones in the northern hemisphere. There is a nice one towards the upper left. What are your conclusions concerning the rotation in the northern and southern hemisphere?
