The Great Plains are located on the North American continent, in the countries of the United States and Canada. The Hub delivers science-based knowledge, practical information, management & conservation strategies, and decision tools to farmers, ranchers, and forest landowners with the goal of helping them adapt to weather variability and … Humans have converted much of the prairies for agricultural purposes or to create pastures. Skold, Melvin D. Agricultural Systems and Economic Characteristics of the Great Plains. Wind speeds are often very high, especially in winter. Schimel, D.S., W.J. Much of the plains experience cold winters and warm summers, with low precipitation and humidity, much wind, and sudden changes in temperature. Some sections are extremely flat, while other areas contain tree-covered mountains. We have a vast array of resources here on our website, including near real-time and historical climate data, national and regional climate data maps, agricultural climate products, and regional climate summaries. Natural vegetation in the Great Plains is dominated by grasses—tallgrass and medium grass prairie in the east and shortgrass and bunchgrass steppes in the west. Heat and water stress from droughts and heat waves can decrease yields and wither crops.18,19 The influence of long-term trends in temperature and precipitation can be just as great.19 As temperatures increase over this century, optimal zones for growing particular crops will shift. The climate of the Great Plains varies greatly from north to south and from east to west. Das Klima gilt als kontinental mit kalten Wintern, warmen Sommern, wenig Niederschlägen und viel Wind.

Rainfall increases significantly from north-west to south-east, the south-east having over 40 inches per year compared to less than 14 inches in some parts of Canada and Montana. Sections with less moisture have lighter, shallower soils with less organic matter, while in the most arid regions the soils are even thinner, lighter in colour, and less organic in composition. Dry, cold masses from Canada bring cold, dry air across the Plains while northward moving air masses originating from the Gulf of Mexico and Caribbean often bring warm, moist air to the region. The soil groups of the Great Plains are correlated with rainfall and natural grass cover. There also remain important questions about the effects of climate change on the northern and southern Great Plains, thanks to the huge variability in the weather. Warmer winters are altering crop growth cycles and will require new agriculture and management practices as climate change impacts increase. Before European settlement, the Great Plains were the home of immense herds of grazing mammals: the buffalo (bison) and the pronghorn. This means that the Great Plains has a less consistent climate due to its central location than a region located on the coast.

Eastern areas are also much wetter than the semi-arid west. The way of life of the Great Plains Indians was dictated by climate, land, natural raw materials available and the animals, fish, birds, plants, nuts, berries and trees. In parts of the region, this will constrain development, stress natural resources, and increase competition for water among communities, agriculture, energy production, and ecological needs.

For over 30 years, the High Plains Regional Climate Center (HPRCC) has been providing the public with access to the most up-to-date climate data and information available. Much of the natural grass cover, however, has been removed to create agricultural land or is heavily overgrazed, allowing for an increase in less-palatable species such as the cactus.

The Great Plains is a vast region of the central United States – so vast, in fact, geographers and researchers sometimes split it into two or three subregions. The resulting configuration is then used to produce regional climate downscaling over the Great Plains for a historical period of 36 years (1980–2015) during which precipitation data are available for verification. The Red River of the North, which forms the border between North Dakota and Minnesota, drains north into Canada. Updates?

ADAPTING TO CLIMATE CHANGE GREAT PLAINS The Great Plains is projected to experience higher temperatures, increased precipitation, and more frequent and intense storms, with a generally hotter southern area and colder northern area. Furthermore, warm, dry air can move up from the south-western deserts and Pacific Ocean air often moves east, crossing mountain ranges that produces a significant warming and drying effect. In the Southern Great Plains, hantavirus, Rocky Mountain spotted fever, leptospirosis, and West Nile virus are all currently endemic and could be impacted by climate change. The Northern Great Plains spans more than 180 million acres and crosses five U.S. states and two Canadian provinces. Indigenous peoples of the Northern Great Plains are at high risk from a variety of climate change impacts, especially those resulting from hydrological changes, including changes in snowpack, seasonality and timing of precipitation events, and extreme flooding and droughts as well as melting glaciers and reduction in streamflows. The southern plain receives an annual rainfall of 15 to 25 inches while the northern plain has 12 to 15 inches of rain in a year. Regional Climate Impacts: Great Plains The Dust Bowl: Combined Effects of Land Use and Climate Over the past century, large-scale conversion of grasslands to crops and ranchland has altered the natural environment of the Great Plains.

Other grassland-adapted animals that thrive together with agriculture include prairie dogs, coyotes, prairie chickens, and rattlesnakes. Agriculture is fundamentally sensitive to climate. The Great Plains have become a locus of climate impact concerns in the United States, given the region's imputed marginality (Opie 1989) and the tendency of climate models to predict a warmer and drier midcontinent in a greenhouse world (Schlesinger and Mitchell 1985; Rosenzweig 1989). The Great Plains are already seeing a great many climate impacts today. In parts of the region, this will constrain development, stress natural resources, and increase competition for water. Thus, states such as Delhi, Haryana, Punjab, and Uttar Pradesh are extremely hot in summers and extremely cold in winters. Grasslands are among the least protected biomes. The region witnesses more rainfallin summer than in winter. In lieu of climate simulations for the 4.2 ka event, the objective of this paper is to examine modern climate analogues as an alternative approach for understanding circulation patterns and potential heterogeneous surface responses between ∼4200 and ∼4000 cal yr BP in the CRM and western Great Plains region. The varying climate of the plains is largely due to the movement of different air masses.
