Tropical Cyclones

6 important questions on Tropical Cyclones

What is the definition of a tropical cyclone?

A tropical cyclone is a large-scale cyclone, originating over tropical or subtropical waters, with a closed surface wind circulation and a well-defined center (the eye).

How does a tropical cyclone form?


1. Tropical disturbance
2. Coriolis effect
3. Warm ocean waters
4. Low values of vertical wind shear

What are low values of vertical wind shear (~10 m/s) between the surface and the upper troposphere needed?

Because high values will disrupt the deep convection and prevent tropical cyclone genesis or weaken or destroy a developed tropical cyclone.

How is the height of the storm surge influenced by?

TC intensity, size, track, and can be amplified by a shallow coastline and local geometry.

Why is there an increase in tropical cyclones intensity?

Increase due to higher sea-surface temperatures (= more fuel!)

Three things you need to know about tropical cyclones and climate change.


1. Tracks: Poleward shift due to increasing SSTs

2. Storm surge: Increase –stronger TCs + sea-level rise (though sea-level rise seems to be the most important contributor)
4. Precipitation: Increase (warm air can hold more moisture!)
