Allergies In The Southwest
The Change In Seasons In The Southwest And How it Affects Allergies.
With beautiful spring weather comes flowering trees and desert plants. The Southwest features a semi-arid to arid climate, depending on the location. Much of the Southwest is an arid desert climate, with some higher elevations. You may wonder why it's so windy during the months of March, April, and May. This time of year allergies seem to increase a lot. The weather is caught in a tug-of-war with a atmospheric instability caused by the increasing strong sunshine. Wind pollinated plants produce comparatively huge quantities of pollen that become airborne easily, and can travel 20 miles or more on a windy day. Therefore most of the pollen found in air samples is derived from plants pollinated by wind. In the southwest there are many species that are native to the region and many introduced species.
