The surface wind field is a smoothed region showing the farthest extent from the

center of 34-, 50-, and 64-knot winds in each quadrant of a tropical cyclone at the

time an advisory is issued. Consequently, it is not an exact representation of

the wind field.

This section shows information about this dataset's attributes
Attributes Range Median Mean Std. Dev.
The sequential number of the tropical cyclone for a particular BASIN according to the time that the first advisory is issued.
