Climate Prediction Center

<h2 id="history">History</h2>
<p>The roots of modern climate prediction can be traced to the work of one of the nation's first applied climatologists, <a href="/facts/Thomas_Jefferson/8yxtcjKK">Thomas Jefferson</a>, third <a href="/facts/President_of_the_United_States/oMsfmLb1">President of the United States</a>. A century later, the federal government assigned to the <a href="/facts/Army_Signal_Corps/xAqQnv2w">Army Signal Corps</a> the mission to define the climate of the regions of the country being opened for farming.
</p><p>In 1890, the <a href="/facts/United_States_Department_of_Agriculture/3PK2rx7C">United States Department of Agriculture</a> (USDA) created the Weather Bureau climate and crops services which began publishing the Weather and Crops Weekly Bulletin, which the CPC in conjunction with the USDA still publishes today.  The records of the Climate Division span from 1883 to 1961.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a>  For a time during the 1960s, the Weather Bureau's Office of Climatology was located in <a href="/facts/Suitland,_Maryland/PyRx6tXX">Suitland, Maryland</a>.
</p><p>In 1970, various federal weather and climate functions were consolidated into the National Weather Service (NWS) and placed in a new agency called the National Oceanic and Atmospheric Administration (NOAA). In the 1980s the National Weather Service established the Climate Prediction Center, known at the time as the Climate Analysis Center (CAC). The CPC is best known for its United States climate forecasts based on <a href="/facts/El_Ni%C3%B1o/HsqetArr">El Niño</a> and <a href="/facts/La_Ni%C3%B1a/SuYNrv9n">La Niña</a> conditions in the tropical <a href="/facts/Pacific/bdxgXRVM">Pacific</a>.

<p>The CPC's products are operational predictions of <a href="/facts/Climate_variability/D3X6Ulbu">climate variability</a>, real-time monitoring of global climate, and attribution of the origins of major climate anomalies. The products cover time scales from a week to seasons, and cover the land, the ocean, and the atmosphere, extending into the <a href="/facts/Stratosphere/taBra67V">stratosphere</a>.
</p><p>These climate services are available for users in government, the public and private industry, both in this country and abroad. Applications include the mitigation of weather-related <a href="/facts/Natural_disasters/cCSK2uH0">natural disasters</a> and uses for social and economic good in <a href="/facts/Agriculture/TGztqzJs">agriculture</a>, <a href="/facts/Energy/wd8PrQM7">energy</a>, <a href="/facts/Transportation/npstdhvc">transportation</a>, <a href="/facts/Water_resources/2j7FJlLE">water resources</a>, and <a href="/facts/Health/yzPVrjTs">health</a>. Continual product improvements are supported through diagnostic research, increasing use of models, and interactions with user groups. Some specific products include:
