Mediterranean observed tracks in 2023

Note on estimated wind speeds

1-minute MSW: Maximum sustained wind (knots) averaged over 1 minute (JTWC Hawaii, NHC Miami, CPHC Hawaii)

3-minute MSW: Maximum sustained wind (knots) averaged over 3 minutes (IMD New Delhi)

10-minute MSW: Maximum sustained wind (knots) averaged over 10 minutes (JMA Japan)


Note: Although 1-minute average winds should be stronger than 3-/10-minute averages, this may not be the case here since estimates are obtained from different warning centres using different analysis techniques.
