Tropical Cyclone NARGIS-08

, ,

The tropical cyclone Nargis in the Bay of Bengal is on course towards the west coast of Myanmar. It is expected to hit the lowest central part of the country, the Ayeyarwady (or Irrawaddy) delta near the great city of Yangon (also known as Rangoon) and the low coast to the north of it. In the northern hemisphere a cyclone rotates counter-clockwise, because of the coriolis force, which means that water masses from the Bay of Bengal will be forced far over land on the right side of the cyclone, where the delta is. Further north the mountain range Arakan Yoma (also known as the Chin Hills) forms a wall towards the bay, and here Nargis is expected to release torrential rains, when the humid air is forced up over the up to 3000 m high mountain tops.

The majority of Burma's Myanmar's population lives in the Ayeyarwady valley. The upper and central portions of the Ayeyarwady delta are almost entirely under cultivation, principally for rice. The climate is monsoonal climate, with an average annual rainfall of about 1,500-2,000 mm in the north increasing to 2,500 mm in the southeast and 3,500 mm in the southwest. Over 90% of the rain falls between mid May and mid November.

Sorry at my age we sometimes have difficulties with "new" geographical names, but I do my utmost to keep to the official, politically correct, spelling.

It is terrible to read your post now, while knowing the terrible consequences of Margis cyclone.
Everything is clearly announced here, and I even haven't read before what the coriolis force was expecting to do there ; hopelessly it was true.

It was a terrible catastrophy, and it was really chocking that the local population in Myanmar were not warned beforehand.
