MOUNT
MAUNGANUI - WEATHER REPORT
Apart
from special waves such as tsunamis, the only thing that produces
the waves we see on our coasts is the action of the wind blowing
over the sea surface. Waves arriving on a coast can be generated
by local wind, in ‘real time’, in which case the waves
are called windsea, or they can be the result of a wind that
blew over the surface of the ocean thousands of kilometres away,
up to several days before, in which case they are termed swell
or groundswell. |
