Definition
Given a vector field 
, where 
and 
represent the components of the winds of each of the annotations.
The vector field representation allow to observe the behavior of the winds in a determined region, these configurations are:
- Vortex
- Confluence
- Difluence
- Saddle Point
The meteorologists annotated the different configurations that it can present in a period of time and a level determined, this process was done with an annotations tool that allow to select this configurations.
Model Mathematic
Given a vector field 
, a way to classify this configurations is through the use of phase portrait, this method is used in the dynamic system to understand the behavior of functions of 2 or more variables. In computer vision is used in the detection corner, mammography and others.
This method allows to construct a equation system in which these can calculate the determinant and the trace. The trace and the determinant indicate as is the behavior of the system like show the figure
