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 consists in to construct a equation system that allows to calculate the determinant and the trace, at calculate those, we can obtain a way of classify this configurations
