填空题An American study has shown a link between activities on the surface of the sun and weather conditions on Earth. Small changes in the sun's (26) can produce effects on Earth, resembling two weather events in warm waters of the Pacific Ocean. The two events are (27) known as La Nina and E1 Nino. Reports say the study may (28) better predictions of temperatures, rainfall and the intensity of weather systems. Scientists measure solar activities by counting dark areas on the sun's surface. These sun spots produce (29) of energy. Other scientists have shown that sun spot activities can be measured in periods of time that last about 11 years. The total energy reaching Earth from the sun rises and falls by just (30) across this solar cycle. In the new study, scientists (31) examined more than 100 years of ocean temperature records. They also used computer programs designed to reproduce the world's climate. They found the highest levels of solar activities cause small, but (32) effects on weather systems around the world. These periods of high activity are known as solar maximum. A report says that at maximum activity, the small increase in sunshine over several years causes a small temperature increase in Earth's (33) . This is especially true in cloud-free areas of the Pacific. The extra heat is enough to cause ocean waters to (34) into the air.
