Map Domain Options

Tropycal offers a variety of pre-defined map domains to use for plotting, passed via the “domain” argument. These are listed below:

Domain	Description
“all”	Global projection, centered on the Prime Meridian.
“north_atlantic”	North Atlantic Ocean basin.
“east_pacific”	East Pacific Ocean basin.
“west_pacific”	West Pacific Ocean basin.
“north_indian”	North Indian Ocean basin.
“south_indian”	South Indian Ocean basin.
“australia”	Australian basin.
“south_pacific”	South Pacific Ocean basin.
“south_atlantic”	South Atlantic Ocean basin.
“conus”	Continental United States.
“east_conus”	Eastern United States.

A custom map projection can be defined for all functions using a dictionary, with keyword arguments corresponding to the map bounds. For example, use “n”, “north”, “N”, or “North” to specify the north bound of the map. Sample usage is listed below:

#One method of creating a custom domain
storm.plot(domain={'n':50,'s':30,'w':-70,'e':-30})

#Another method of creating a custom domain
storm.plot(domain={'north':50,'south':30,'west':-70,'east':-30})

The following domains are available for some, but not all plotting functions. Please refer to the specific function documentation to see if these projections are available.

Domain	Description
“dynamic”	Dynamic map projection, centered on the feature of interest (e.g., storm track, tornadoes, recon data).
“dynamic_forecast”	Dynamic map projection, focused entirely on the forecast track. Available only for forecast track plotting functions.
“dynamic_tropical”	Dynamic map projection, excluding extratropical cyclone points. Available only for track plotting functions.
