I set the filters in my Hotmail to remove as spam anything with numbers
in it. Which took the EO-Announcements out of my post box. Hence I missed this gem until I realised that i had not received anything from them for a while. "In the summer of 2005, the Bermuda High has been extended to the south and west, letting Hurricane Alley bake under relatively clear skies. Since one of the ingredients necessary for a hurricane* to develop is warm ocean water (at least 28 degrees Celsius or 82 degrees Fahrenheit), this streak could lead to more hurricanes during the 2005 season. On August 2, the National Oceanic and Atmospheric Administration (NOAA) increased their predictions for the 2005 season, warning that 11-14 storms may form between August and November in addition to the 9 that have already pushed through the Atlantic." http://earthobservatory.nasa.gov/New...es/images.php3 *Extra Tropical Hurricane that is. Also in the bulletin is a picture of the Portuguese fires. My wacky code is as out of synch as it ever was so I predict the predictions may even top their errr... ahem, prediction. Interesting spin on anticyclones: "A high-pressure system pushes air down toward the surface, causing it" the air in the anticyclone, that is "to warm and dry out. In the warmer, drier air, fewer clouds form to shield the ocean from the sun, allowing water temperatures to rise." We know of course that the hurricanes are superseded by quite dense clouds and are for a considerable period. But the point that struck me is that the heat itself may be causing the spin. It might be shown some how that the expansion it causes can in fact explain why the surface of the sea mirrors the weather pattern above it. But how? Well, suppose for one outlandish moment that it is not the moon's "pull" that causes tides per se but the diurnal expansion of the surface of the sea. Where is it going to go and which way? And why is it contained in the lower half of the North Atlantic? It beggars belief that the anticyclonic direction is caused by Coriolis’ “Effect”, so why do they spin the way they do? That’s a deep one. -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |
