Persistent Wind Intensity Patterns in Historical Typhoon Tracks Beyond 180 Degrees Longitude #831

Issue Description:

I'm encountering consistent patterns while plotting wind intensity for historical typhoons that occurred in Fiji using CLIMADA v4.0.1. I'm using the TropCyclone class from climada.hazard and extracting tracks from specific Fiji historical typhoons via TCTracks.from_ibtracs_netcdf().

Problem Statement:

The issue arises consistently when dealing with typhoon tracks where longitudes exceed 180 degrees. Despite the typhoons occurring in different years, the wind intensity patterns remain unchanged in these regions. Notably, this occurs when analyzing typhoons such as Tomas in 2010, Evan in 2012, and Yasa in 2020.

Steps to Reproduce:

  • Use TCTracks.from_ibtracs_netcdf(storm_id) to extract tracks for historical Fiji typhoons. For instance, consider typhoons Yasa (id = 2020346S13168), Tomas (id = 2010069S12188), and Evan (id = 2012346S14180) as examples for track extraction.
  • Employ the TropCyclone.from_tracks(track, centroids, store_windfields=True) function to derive windfields for each historical typhoon track. Specify centroids to locate the area of interest (Fiji). While optional, defining centroids allows focused analysis on the targeted region (Fiji) instead of the entire globe during windfield plotting.
  • Generate wind intensity plots based on the extracted tracks using TropCyclone.from_tracks().plot_intensity(storm_id).
  • Observe and analyze wind intensity patterns specifically in regions where longitudes surpass 180 degrees.

Sample figures depicting wind intensity patterns for typhoons Tomas 2010, Evan 2012, and Yasa 2020 are attached below.
The issue persists across different typhoon events despite variations in their occurrence years.

Your assistance in addressing this issue would be greatly appreciated.
