anyone ever wonder what drives a hurricane's direction and how projected paths are forcasted?? for example what is causing hurricane bill to vear off to sea and miss slamming new jersey and new york? is it the positioning of the bermuda high holding it off our coast?? anyone with knowledge please reply.
I think it has to do with pressure systems and the jet stream. I mean, in general, the jet stream is always blowing away from the east coast. It really only varies northerly and southerly, but its always predominantly westerly. What the hell do I know though?
http://weather.unisys.com/nam/4panel/nam_500_4panel.html I'll take a stab at this...if you look at the above link you'll see a trough building in from western canada over the next few days. This will steer the storm away from the coast due to the increase in upper level winds. Not sure what causes a storm to accelerate though.
i know: the military throws massive gel bombs in the water that soak up tropical moisture. this makes the air to dry so they curve away. i invented them. the tropical storms eat water and piss it all over the place. so there you have it.
primarily the upper air patterns drive the circulation below. The atmosphere is a giant sphere of fluid, moved by the earth's rotation and variability of the distribution of solar radiation (among other things). In Bill's situation, the Bermuda High pressure parked above him, has steered Bill off to the W and WNW.. Air moves clockwise around a High. As Bill, gets off to the west of the High pressure in a couple days, he will be less influenced by the High Pressure and pushed northward due to a weak low pressure trough centered in Canada but stretching down the Eastern Seaboard. As the trough pushes eastward, Bill will move N and E. Hope that helps.
well for bill the only reason its heading up north so far is because a low pressure system split right at the east coast line so as bill begins to move these now two low pressure systems must move in one direction and this time the system to the west happenedd to be stronger than that to the east therefore the storm heads for the east coast and then will gradually vere off to the east and disappear at sea
