CIRA - Probability of TC Formation

This image shows the latest SSTs. The red boundary separates the temperatures above and below 26 C, the temperature needed to support tropical cyclone development.

(Depth of 26 C Isotherm)

In addition to warm SSTs of over 26 C, these warm temperatures need to have a depth of around 50 meters in order for a tropical cyclone to sustain itself. This image shows the depth of the 26 C isotherm.

Wind Shear Analysis

(Click images for larger version)

Wind shear is a change in wind velocity (speed and/or direction) with height. Shear can rip a tropical cyclone apart or keep one from forming by preventing the convection from building. The following images show the latest wind shear and the shear tendency - whether it is increasing or decreasing.

This chart represents the 24-hour change in wind shear (shear tendency). 

Upper level divergence is when the air in the upper levels of the atmosphere is moving away from a common area. It can induce sustained updrafts and therefore provide the exhaust system for a tropical cyclone, allowing it to strengthen.

Lower level convergence is when the air in the lower levels of the atmosphere is coming together in a relatively small area - the opposite of divergence. Eventually, there is nowhere for the air to go but up.

The steering winds in the atmosphere can help us determine the path and speed of a tropical cyclone. One rule of thumb says that the cyclone will move in the direction of the steering currents, but at about half the speed. However, the steering layer we need to look at is based on how deep the tropical cyclone is. We can determine this from the minimum pressure and then use the appropriate image below.
 
Steering Layer (MSLP 1000-1010mb)
 
Steering Layer (MSLP 990-999mb)
 
Steering Layer (MSLP 970-989mb)
 
Steering Layer (MSLP 950-969mb)
 
Steering Layer (MSLP 940-949mb)
 
Steering Layer (MSLP 940mb or less)
