| 31. | Most often, haze is found in the middle latitudes during the summer season when the winds aloft become very light.
|
| 32. | In summer, when middle latitude storms are much weaker, tropical storms, both benign and destructive, help balance the weather budget.
|
| 33. | In the middle latitudes, far from both the Equator and the poles, variations in the length of daytime are moderate.
|
| 34. | In the middle latitudes, these rivers typically flow strongly and predictably, powered by growing temperature contrasts of the cool season.
|
| 35. | A few days after a typhoon reaches the middle latitudes of the western Pacific, eastern North America typically turns colder.
|
| 36. | But, this storm, like most hurricanes, will perform the important function of moving heat from the tropics toward the middle latitudes.
|
| 37. | This explains why most of coastal North America in the middle latitudes experiences dry summers, despite abundant rainfall in the winter.
|
| 38. | This is a channel of strong winds embedded within the general westerly flow of air across the middle latitudes of Earth.
|
| 39. | Called the subtropical jet stream, this low-latitude jet can be an important conveyor of moisture into the middle latitudes during winter.
|
| 40. | But the Arctic Oscillation, a wind pattern that affects the frequency of chill in the middle latitudes, is also at work.
