There were no tropical cyclones reported in the Central North Pacific during 1977. The Western North Pacific experienced the smallest number of typhoons (11) since JTWC's formation in 1959. Eastern North Pacific activity was also at a minimum; only 8 tropical storms or hurricanes were reported during the year in that area--the lowest number since 1966 when excellent satellite full coverage began.
Also, the Atlantic was very quiet, one of the least active on record. Normally a somewhat quieter Pacific season mean a more active Atlantic generally speaking. I know the Southern Hemisphere saw 25 total storms, which is somewhat below average of 28. The North Indian Ocean saw 6 storms, which is slightly above average. I always wondered about why 1977 was so quiet in almost all the Basins. It was a neutral year in terms of ENSO, other than an El Nino in some months. I looked looked Daily Mean Composites
and the SST anomaly was below average in general. As for pressure anamoly, it was above average.
