Because El Nino was so evident last year, it is very possible
there will be a drought this year. The government should
immediately implement water-conservation measures. Normally, the
equatorial trade winds in the Pacific Ocean blow toward the
west. These winds carry warm surface water to the west Pacific.
A large portion of the western Pacific has a sea surface
temperature of over 28?C. Because tropical depressions, which
beget tropical storms and typhoons, are often formed in areas
with sea surface temperatures higher than 27?C, most of them
occur in the tropical region of the western Pacific. There are
an average of 27 typhoons per year. Each year, typhoons strike
Taiwan 3.7 times on average. As the trade winds blow warm
surface water to the west Pacific, the sea level in the western
Pacific is 60cm to 90cm higher than that in the eastern Pacific.
Statistics show that El Nino, on average, happens once in two to
five years and its strength varies each time, meaning that it
has more to do with the yearly cyc
