Every year in late December, a southward-moving current warms the water along the Pacific coast of Peru. Because the warm current arrives around Christmas, the Peruvians named it El Nino, "boychild". Until the mid 1970s, El Nino was an unrecognised local phenomenon, until scientists began to realise that El Nino, later named EI Nino Southern Oscillation (ENSO), is part of a huge ocean and atmosphere system that is felt as far away as Australia and Indonesia.
Every few years the El Nino current is warmer than normal, causing greater ocean warming and consequently changes in the normal patterns of sea and surface temperatures. The resulting changes in atmospheric pressure affect trade wind speeds and the location of the largest thunderstorms, thus affecting weather patterns around the world. The shift in location of the Pacific's largest thunderstorms, which usually occur from the Western Pacific to the Central Pacific, changes global weather patterns because the thunderstorms pump air into the atmosphere in different places than normal. The result is a shift in the location of high- and low-pressure areas, wind patterns, and the paths followed by storms.
From 1982 to 1983 the El Nino condition caused greater than average precipitation along the US West Coast and sent five hurricanes to French Pollynesia, which normally goes years without hurricanes. That same year, El Nino was linked to floods in Louisiana, Florida, Cuba, Ecuador, Peru, and Bolivia, and to droughts in Hawaii, Mexico, Southern Africa, the Philippines, Indonesia and Australia.
In response to the 1982-83 global weather disruption, the World Meteorological Organization initiated the Tropical Ocean and Global Atmosphere (TOGA) program. The goal of the 10-year program is to gain a better understanding of El Nino so scientists can forecast future El Nino episodes and their likely results.

Between the months of November and May, a wind blows from the west in most part of Indonesia. It comes from ocean and carries rain. Clouds build up around the mountains, and every afternoon rain falls. The rain is always heavy, and rivers now become dangerous. When it rains the whole day, they may suddenly overflow and cause great damage to the land.
Most farmers are glad when the wet season begins. There is water for their fields and they can again start growing rice. But people in town are not so glad for the streets soon get muddy and dirty. They prefer the dry seasons when they can sit outside and enjoy cool evening.

2. What causes the rain?
A. Clouds building up around the mountains
B. The afternoon
C. The mountains
D. The ocean
3. What damages the land?
A. The wet season B. The overflow of the rivers
C. The dry season D. The sudden rain
4. Why can farmers start growing rice again?
A. Because the land has been damaged. B. Because the river overflow.
C. Because there is water for their fields. D. Because the dry season has begun.
5. Why are people in town not so happy in the wet season?
A. Because the streets are full of mud. B. Because the evenings are cool.
