Storm Track Controls
Overview

The Storm Track Control displays tropical storm observation and model output tracks. Currently the McIDAS-V supports both the Automated Tropical Cyclone Forecasting System (ATCF) data as well as data from the Shanghai Typhoon Institute.

To load in ATCF data select the Tools->Text Data->ATCF Tropical Storm Data menu item in the Main Display window. This creates a data source with a predefined path to the National Hurricane Center ftp site. Then, create the Storm Track display.

The display control shows the set of available storms on the left panel organized by year and basin, e.g., Atlantic (AL), Eastern Pacific (EP) and Central Pacific (CP).

Year Display

At the top of the list is an option (Yearly Tracks) which allows the user to display the observed tracks for all the storms in a given year. You can load and/or unload any number of years worth of observed tracks. The color swatch changes the color of the tracks for a given year. The Time Mode menu allows one to change the animation mode, e.g., use the year or use the storm start time.

Storm Display

To show the observation and all of the model results for a single storm select the storm in the list and press the Load Tracks button button. You can load any number of storms but they are shown in different panels. You can use the View->Storm Tracks menu to list out all of the loaded storms, remove them all, etc. Once a storm is loaded it can be removed with the Remove Storm icon icon shown in the upper right.

Once a storm is loaded the first thing you should do is to specify which "Techs" (or models) to use by bringing up the control's Properties dialog Edit->Properties menu. Use Ctrl+A to select all items in the tab, the left/right arrows to remove/add an item from/to the Use column, or Delete to remove an item from the Use Column.

Storm Chart

The Storm Chart tab shows time series charts of selected tracks. Under the main Edit menu you can any number of new forecast time or forecast hour charts. The forecast time chart is based around the model run time of the selected forecasts. The forecast hour charts selects data across the different model run times, e.g., you can show the 12 hour forecast from each model run.

To do the charting of the storm track, one or more Techs need to be selected. Once selected the Forecast Hour/Forecast Time list is populated. One or more times can be selected (Ctrl+click). Each Parameter that is selected will result in a new chart shown on the right.
