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.
The normal breathing rate for a 4 month old baby is between 30 and 60 breaths per minute.
Preschooler (3-5 years): 22-34 breaths per minute; School-age child (6-12 years): 18-30 breaths per minute; Adolescent (13-17 years): 12-16 breaths per minute; Periodic Breathing in Children. Infants usually have a much faster respiratory rate than older children, and can also exhibit a phenomenon referred to as periodic breathing.
