It seems they never interpolated the storm tracks resulting in these weird strings of circles and arcs? And whatβs up with the lack of data in the south? While #TropicalCyclones typically donβt form near nor approach the equator, the hard cutoff at around the 6.6Β°N latitude is an interesting choice.
Anyway, I can spot 2012βs Typhoon #Bopha / #PabloPH in #Mindanao and 2013βs Typhoon #Haiyan / #YolandaPH in the #Visayas, which tells me that they did use historical data.
