calc_forward_speed

A numeric vector giving latitude of the first location
(degrees)

tclat_1

A numeric vector giving longitude of the first location
(degrees). This value should be expressed as a positive value for Western
hemisphere longitudes.

tclon_1

A date-time vector giving the time of the first observation.

time_1

A numeric vector giving latitude of the second location
(degrees)

tclat_2

A numeric vector giving longitude of the second location
(degrees). This value should be expressed as a positive value for Western
hemisphere longitudes.

tclon_2

A date-time vector giving the time of the second observation.

time_2

This storm takes two storm locations and their observations times and
calculates the average speed of the storm between the two observations.

Allows users to input tracking data for a hurricane
or other tropical storm, along with a data frame of grid points at which
to model wind speeds. Functions in this package will then calculate wind
speeds at each point based on wind model equations. This modeling framework
is currently set up to model winds for North American locations with
Atlantic basin storms. This work was supported
in part by grants from the National Institute of Environmental Health
Sciences (R00ES022631), the National Science Foundation (1331399), and the
