In southern New Mexico and Arizona, shallow marine deposits, laid down when the ice in Gondwana retreated and sea level rose, alternate with layers of dust blown in when the ice in Gondwana advanced and sea level fell.

Today nearly all the glaciers in the Southwest are gone, and the climate is in an arid state.

In New Mexico, for example, average annual precipitation ranges from less than 25 centimeters (10 inches) within the Great Plains and Basin and Range regions to more than 50 centimeters (20 inches) at the higher elevations to the northwest. Left:Lake Bonneville's maximal extent during the Pleistocene. For example, high winter temperatures between 2000 and 2003 correlated to bark beetle outbreaks that devastated pinyon pine throughout the Southwest, leading to nearly 90% mortality at some sites in Colorado and Arizona. Temperature and drought data come from a network of thousands of weather stations overseen by the National Weather Service. Annual Weather SummaryNovember 2022 to October 2023.

Frequent showers and thunderstorms continue well into the summer. As in Arizona, the desert experiences a large range of temperature on a daily basis. Some earlier studies suggested that El Nio may be related to lower JulyAugust rainfall, and La Nia related to higher rainfall, due to large-scale atmospheric circulation changes.

When you add in the sparse rain-gauge observations available in the U.S. Southwest and Mexico, it becomes even more difficult to make confident statements about the effects of the monsoon and how it can be predicted. (1) The North American Monsoon, published in the Bulletin of the American Meteorological Society by David Adams and Andrew Comrie, provides a comprehensive overview of the North American Monsoon and related research through the late 20th century. Northwestern Mexico receives upwards of 75% of its average annual precipitation from it, and Arizona and New Mexico more than 50%, during JulySeptember. JulyAugust rainfall anomaly averaged over North American Monsoon region for every year 19502019 (y-axis) versus Nio-3.4 index (x-axis). Climate change and drought in the American Southwest I listened to the Southwest Climate Podcast from CLIMAS, the Climate Assessment for the Southwest, to learn more about what affects the monsoon and its rainfall, and how Monsoon 2021 is shaping up, and reached out to the podcast co-hosts, Zack Guido and Mike Crimmins, for help with this post.

Brown indicates where precipitation has been less than average; green is greater than average. Zack and Mike mention that last year was an extremely dry monsoon, and this year is extremely wet.

Grande (2013) The Lost World of Fossil Lake. The American Southwest, here defined as the area between 95W and 125W and 25N and 40N, 9 covers over four million square kilometers. The Great Plains receive warm, moist air moving north from the Gulf of Mexico, and cold, dry air moving in from the Rocky Mountains and the northern U.S. Where these air masses meet, vigorous mixing causes thunderstorms. This page uses Google Analytics. In New Mexico, climate is characterized by arid, semiarid, or continental conditions, with light precipitation, low humidity, and abundant sunshine. That timeworn classic is only partially true--May and September can also be great summer months. (3) There is a whole lot of interesting detail in this reportabout everything, but about the North American Monsoon specifically. Map made by Elizabeth J. Hermsen usingSimplemapprand modified in Photoshop. Figures 2 and 3 show two ways of measuring drought in the Southwest: the Drought Monitor and the Palmer Drought Severity Index. A blog about monitoring and forecasting El Nio, La Nia, and their impacts. Check out Toms recent post on the drought in Arizona to understand more about how drought works in this region. As Pangaea reached its greatest size during the early Triassic, the monsoons intensity increased, and the vast dune deserts of the late Permian were replaced by rivers and floodplains. This feature focuses on six states that are commonly thought of as southwestern and characterized at least in part by arid landscapes and scarce water supplies: Arizona, California, Colorado, Nevada, New Mexico, and Utah. 830 AM EST Thu Feb 16 2023. North America and Europe are part of Laurasia, and South America and Africa are part of Gondwana. An increased frost-free season length also leads to increased water demands for agriculture and heat stress on plants. Likewise, its not yet clear how the monsoon is changing in the warming climate, or how it will in the future.

In 2020, Colorado ranked 7th in the nation for solar and wind power production, and Arizona and New Mexico ranked 12th and 13th, respectively. . Photoandreconstructionby National Park Service/NPS (public domain). Extent of the Western Interior Seaway during the Cretaceous Period. One controversial hypothesis proposes that an area of western Coloradoone of the islands that dotted the early Carboniferous seawas, in fact, glaciated. We are largely unaware of this precipitation because of the Southern California Chamber of Commerce and a lack of rain gauges. Fossil ammonoid (Nigericeras scotti) from the Late Cretaceous Greenhorn Limestone, Baca County, Colorado. As of June 2022, it was more than 90% contained. Acad.
