Prevailing winds and pressure belts are major climate controls. A belt of low pressure known as the intertropical convergence zone (ITCZ) lies along the Equator. On either side of the equatorial low, between 25Â° and 30Â° latitude in each hemisphere, is a belt of high-pressure centers over the oceans. From the equatorial side of these subtropical highssuch as the Hawaiian high.

By now, your baby's internal clock has kicked in, and he can differentiate between day and night. He should be on the way toward an established sleep pattern. During this time, babies need an average of 14 hours of sleep per day: At 4 months, a baby can go eight hours at night without a feeding; by 5 months, he can sleep for 10 or 11 hours straight. Babies will sleep four to five hours during the day, spread out over three naps.
