Calculate winds parallel and perpendicular to shore.

Background

Wind data available at NOAA PSL. It comes in two forms ‘U-wind’ and ‘V-wind’. u-wind is positive for a west to east flow (eastward wind) or perpendicular to the coastline and the V-wind is positive for south to north flow (northward wind) or parallel to the coastline.

Action

Wind Indicator

  1. Downloaded monthly mean dataset (uwind, vwind) from NOAA PSL.
  2. Mask to bluefish polygon
  3. Extract max wind for that day
  4. calculate hypotenuse and angle for each month

Theory

Dataset

Initial Exploration Plots

  1. Downloaded test dataset (uwind 2021, vwind 2021) from NOAA PSL.
  2. Mask to bluefish polygon
  3. Extract max wind for that day
  4. Plot X = day of year, y = mean wind direction.
  5. Repeat for month mean data
  6. Calculate mean seasonal for each year (1:3 = winter, etc.)
