Question about hurricanes?

Question

I'm no expert with weather but I was just curious about hurricanes. Do hurricanes "stop" when they hit land, or do they keep moving onto land? I asked somone a while ago and they said they stop when they hit land, and disperse into t-storms and sometimes tornadoes? So I guess my question is, is this true? And also do hurricane mainly effect cities/towns on the coast?

Answer 1

Ground friction weakens the hurricane because part of its energy is expended as it moves across the mountains, forests, cities, etc.  Then, when the low pressure area reemerges again over warm water, it recharges and intensifies.  As a corollary, the hurricane gets it's energy from the warm water so when over land, its main energy source is unavailable.

Answer 2

Hurricanes weaken as soon as they go over land. People living in the coast are more affected by hurricanes. While theyre on land they could form tornadoes. A hurricane could move through land but it weakens as it goes through

Answer 3

Hurricanes begin in warm waters and lose strength when they move over cooler waters/oceans.  When it hits land, it loses strength because it is no longer over the ocean where it draws its power from.  When it hits land, it doesn't stop, but just breaks down over a period of a day or two.  The winds decrease and they usually go from hurricane status over water, to tropical storm and/or tropical depression over land, then when the winds decrease below tropical storm/depression status, the weathermen call it 'remnants' of the hurricane.  It becomes disorganized over land and, in time, it'll become mere 'remnants' - rain and some gusty winds. The risk for tornadoes decrease as the storm winds down over land.  The tornado and thunderstorm threat usually occurs as the storm gains strength over water and when it first hits the coast.

Answer 4

Because the land lacks the resources (like humidity and temperature changes) the ocean has to feed the hurricane, it starts slowing down as soon as its center hits the land.

But it doesn't slop as soon as it (the center) hits the land, instead the the sustained wind speed drops below 73 mph (t-storm) in 12 hours and below 40 mph in 24 hours generally. As the ground speed of the hurricanes are around 15-25 mph generally and tend to decrease once on land they can generally travel short distances on land. Gustavson's wind speed is expected to drop below 30 mph before it is midway up TX.

As it (sustained wind speed) slows down, its path tends to shift westward at USA.

Answer 5

No, they typically just keep on moving inland, pushed along by the atmospheric steering currents.  Now once they do this, they lose their source of energy, that being the deep warm tropical waters, and they weaken.  As they do this, they tend to spread out more and become prolific rainmakers, causing even more problems with inland flooding.

Answer 6

i dont know but thats scary.

i think im okay with earthquakes for now

Answer 7

they keep on moving on land but they get smaller and smaller if they move further inland because these hurricanes get stronger from warm waters.. and if they are on land there nothing to feed them so they just keep moving and turn to a low pressure..

and yes they do effect more cities/town on the coast because that's where the strongest part of the hurricanes hits first and when they go further inland they get weaker so the city in inland wouldn't be as bad as the city on the coast.

Good Luck.

Answer 8

The more they travel inland the less they have the fuel that feeds them...they slowly degrade until they become a low pressure system.
