Littoral Sand Budget, Hawaii — Chamberlain 
183 
wave types into which the total yearly wave 
spectrum can be conveniently broken, there 
exist other wave types which are too difficult to 
identify or are insignificant to the nearshore 
zone and beaches, either because of their small 
magnitude or because of their infrequent oc- 
currence. Foremost of these are Typhoon Waves , 
produced in the equatorial and southern latitudes 
during the passage of tropical storms. Usually, 
these waves approach from the southeast through 
the southwest and are most likely to occur in 
August and September.
