Introduction

xTime-series for space varying wind velocity components (east-west and south-north) and atmospheric pressure on a Spiderweb grid can be used to simulate the impact of tropical cyclone. 

Usage of the toolbox

Computes The Tropical Cyclone toolbox makes it possible to computes wind field and pressure drop generated by a cyclone. “Draw track” All it takes are basically three steps

1. Determine the track of the cyclone
   1. 'Draw track' is used to draw a cyclone track with

1. 1. the mouse
      1. First select the time (start and time step) 
      2. Secondly determine other settings like Rmax or Pdrop. Which settings can selected depends on the 'Method selected in the Toolbox. Default is the Vmax, Pd and Rmax approach
   2. 'Load track' is used to load an previous saved track which was defined in Dashboard
   3.  It is also possible to load tracks of cyclones (
