Science Earth Science Exercises for Weather & Climate (9th Edition)

How the fact that “Subsidence is typically weaker to the west and stronger to the east of the high-pressure center” as well as “wind patterns and ocean temperatures” contributes to summer dryness in Los Angeles and summer precipitation pattern in Charleston. Introduction Los Angeles' summertime climate is significantly influenced by the subtropical high-pressure system over the Pacific Ocean, also referred to as the Pacific High. The subsidence zone is weaker to the west and stronger to the east of the high-pressure center, which is offshore and to the west of Los Angeles. The air near the ground becomes cooler and more humid than the air above it, creating a temperature inversion. As a result, vertical mixing is less likely to occur in the air near the ground, limiting the production of clouds and precipitation. Explanation Los Angeles's summertime dryness is also influenced by wind patterns. The area is mostly influenced by breezes from the west, which bring chilly, humid air from the Pacific Ocean inland. However, the high-pressure system forces the air to descend and warm, which lessens its capacity to hold moisture. The amount of moisture that can be evaporated from the surface and moved inland is further constrained by the relatively cool water temperatures off the coast of California. In contrast, the Bermuda High, a subtropical high-pressure system positioned over the western Atlantic Ocean, influences the summer precipitation pattern in Charleston. The Bermuda High affects the wind patterns across the Southeast United States and is at its strongest in the summer. The region's predominant winds originate in the southwest, which brings warm, humid air from the Atlantic Ocean and the Gulf of Mexico. The Bermuda High forces the air to sink and warm, which lessens its capacity to hold moisture. On the other hand, the air has plenty of moisture to pick up as it goes inland due to the warm ocean temperatures off the coast of Charleston. Thunderstorms and convective precipitation form throughout the afternoon and evening when the moist air rises over the coastal plain and the Appalachian Mountains. Charleston experiences a wetter summer than Los Angeles due to frequent thunderstorms and convective precipitation.
