Python interfaces for observational data surrounding named storm events

Project description

StormEvents

tests build codecov version license style

stormevents provides Python interfaces for observational data surrounding named storm events.

Usage

storm interface

you can instantiate a new StormEvent object from the NHC storm name and year (i.e. FLORENCE 2018, the NHC storm code (i.e. AL062018), or the USGS flood event ID (i.e. 304).

from stormevents import StormEvent

florence2018 = StormEvent('florence', 2018)
paine2016 = StormEvent.from_nhc_code('EP172016')
sally2020 = StormEvent.from_usgs_id(304)

you can then retrieve track data from NHC, high-water mark data from USGS, and water level products from CO-OPS for this storm

by default, these functions operate within the time interval defined by the NHC best track

from stormevents import StormEvent

florence2018 = StormEvent('florence', 2018)

track = florence2018.track()
high_water_marks = florence2018.high_water_marks()
water_levels = florence2018.tidal_data_within_isotach(isotach=34)

vortex tracks from the National Hurricane Center (NHC)

list storm events defined by the NHC since 2008

retrieve spatial storm tracks provided by the NHC

from stormevents.nhc import VortexTrack

# retrieve vortex data from the Internet from its ID
vortex = VortexTrack('AL112017')

# you can also use the storm name and year in the lookup
vortex = VortexTrack('irma2017')

# write to a file in the ADCIRC `fort.22` format
vortex.write('fort.22')

# read vortex data from an existing ATCF track file (`*.trk`)
vortex = VortexTrack.from_atcf_file('atcf.trk')

# read vortex data from an existing file in the ADCIRC `fort.22` format
vortex = VortexTrack.from_fort22('fort.22')
