1. Storm Tracks Only: Seasonal storm tracks are color coded for intensity with weaker storms in black, purple and stronger storms in orange and red. 2. Storm Frequency: The total number of storms (closed circulation centers binned into 5 x 5 degree grid boxes) during the season. A storm is only counted once for a given grid box and to be counted the storm must have lasted for at least 24 hours. 3. Tracks/Total Precipitation: Seasonal storm tracks with seasonal total precipitation (mm) 4. Tracks/925 hPa Wind: Seasonal storm tracks with seasonal mean 925 hPa anomalous wind vectors and magnitude (m/s, shaded) 5. Tracks/500 hPa Height: Seasonal storm tracks with seasonal mean 500 hPa height anomalies (m) 6. Tracks/200 hPa Wind: Seasonal storm tracks with seasonal mean 200 hPa anomalous wind vectors and magnitude (m/s, shaded) |
