A question about the storm surge.

If I visualize this correctly, at the base of the cyclones eye at ocean level, the wind rotating fast over ocean water pulls all that extra water from hundreds of kilometers away which then moves along with the storm. The extra water is rotating around with the cyclone?

What amount of water gets sucked up into the air to become rain and what amount of water stays in the ocean, does it swell up?

It would be interesting to see an animated three dimensional view of the ocean water rising above sea level then receding back down again. if that’s what happens?

Have any satellites captured video footage of a storm surge?

I’d like to see a time lapse of the first stage when the water gets sucked away.

the water is drawn to the low pressure in the cyclone/hurricane due to the higher pressure pushing down outside the storm. like you “sucking” up liquid through a straw.

In some areas like around Houston storm surge is exacerbated by removing mangroves and worse digging straight channels to allow ease of shipping, the surge just juggernauts down those channels.

It’s complex..

“Anticyclones aloft can form within warm core lows such as tropical cyclones, due to descending cool air from the backside of upper troughs such as polar highs, or from large scale sinking such as the subtropical ridge.”

This.

The oceanic water is not rotating with the cyclone.

Also, water “sucked” into the air by evaporation.

I doubt meaningful storm surge imagery has been captured by satellites. There’s very thick cloud cover for most of the storm and lots of heavy rain is happening.

ok

It would be great if scientists could prepare drones to video-graph the surges

drones that can take all that wind buffering

planning, preparation and timing is needed

it would be like planning for an eclipse but only have days / hours to do it

it would be a great project

very fast science

Maybe a three layered approach using drones at different levels

some drones can be placed on the water, these will move along with the storm

while other drones fly through it,

while others again are over the top of it

there are a number of ways to collect the information

the drones could relay all the information to aircraft higher up over the storm or keep it stored aboard for latter retrieval

Thousands of water proof drones could float on the water once they have collected their information, to be collected later using beacons which another drone ship could do.

There are plans to use drones in cyclones.

A plane could drop drones over the storm and they pass though it land on the water.

In that case it’s a very good question. Is storm surge due to air pressure or wind? My understanding is that it’s due to wind not air pressure. I did some work for CSIRO on “fetch”, which is the distance across the ocean or other body of water over which the storm’s wind causes the waves to develop. So I can categorically say that for short distances the waves grow in height and for longer distances the height stays almost constant as the wavelength gets longer.

But that’s waves, not the same as storm surge. So I could be wrong.

There are computer simulations of hurricane storm surge. Have a look particularly at figures 15 and 17 of A Basin- to Channel-Scale Unstructured Grid Hurricane Storm Surge Model Applied to Southern Louisiana

In that simulation, the storm surge is due to wind, not pressure drop. So I’m right.

I wonder if there’s a ewe tube on this? There is this video simulation of Storm Surge at Townsville. “Green Cross Australia has partnered with CSIRO to produce a stunning visualisation of the storm surge impact caused by a low pressure system such as a cyclone, hurricane or east coast low.” https://www.youtube.com/watch?v=q6GVFWHva4k

On a larger scale, there is this storm surge simulation of Hurricane Sandy in Chesapeake Bay. https://www.youtube.com/watch?v=VXapXdRQxGw

On an even smaller scale, there is this startling 3-D storm surge simulation. https://www.youtube.com/watch?v=meKVxT5Hc2A
