What is the difference between a hurricane and a post tropical cyclone?

Hurricanes and tropical storms often transition to cold core cyclones. When the National Hurricane Center concludes that a tropical storm has transitioned to a (cold core) mid-latitude storm it will designate it as “post-tropical” meaning that it has transitioned to a non-tropical storm.

What is an invest in weather?

An invest is an area that meteorologists and the National Hurricane Center are monitoring for potential tropical development. Think of it is a “precursor” to a possible depression or tropical storm. It is an area of interest that has the potential to become a full blown tropical cyclone.

What does ese mean in weather?

ESE. East-south-east or east-south-easterly.

Where do hurricanes draw heat from?

The actual process begins with a cluster of thunderstorms moving across the surface of the ocean. When the surface water is warm, the storm sucks up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. If wind conditions are right, the storm becomes a hurricane.

Can a post tropical cyclone regenerate?

Early on September 22, the National Hurricane Center noted that regeneration into a tropical cyclone was a distinct possibility. The remnant low pressure area soon moved over warmer seas and a low-shear environment, causing deep convection to re-develop.

What does M stand for in hurricane?

M: Major Hurricane – wind speed greater than 110 MPH.

Why can’t hurricanes form at the equator?

Observations show that no hurricanes form within 5 degrees latitude of the equator. People argue that the Coriolis force is too weak there to get air to rotate around a low pressure rather than flow from high to low pressure, which it does initially. If you can’t get the air to rotate you can’t get a storm.
