), officially the State of Washington, is a state in the Pacific Northwest region of the United States.Named after George Washington, the first President of the United States, the state was made out of the western part of the Washington Territory, which was ceded by Britain in 1846 in accordance with the Oregon Treaty in the settlement of the Oregon boundary dispute.It was admitted to the Union as the 42nd state in 1889. Washington is sometimes referred to as Washington State to distinguish it from Washington, D.
For Washington this means prevailing winds from the northwest bring relatively cool air and a predictably dry season.
In the autumn and winter, a low-pressure cyclone system takes over in the north Pacific Ocean, with air spiraling inward in a counter-clockwise fashion.
Major factors determining Washington's climate include the large semi-permanent high pressure and low pressure systems of the north Pacific Ocean, the continental air masses of North America, and the Olympic and Cascade mountains.
In the spring and summer, a high pressure anticyclone system dominates the north Pacific Ocean, causing air to spiral out in a clockwise fashion.
Despite western Washington's having a marine climate similar to those of many coastal cities of Europe, there are exceptions such as the "Big Snow" events of 1880, 1881, 18 and the "deep freeze" winters of 1883–84, 1915–16, 1949––56, among others.
During these events western Washington experienced up to 6 feet (1.8 m) of snow, sub-zero (−18 °C) temperatures, three months with snow on the ground, and lakes and rivers frozen over for weeks.
Livestock and livestock products make important contributions to total farm revenue, and the commercial fishing of salmon, halibut, and bottomfish makes a significant contribution to the state's economy.
Manufacturing industries in Washington include aircraft and missiles, shipbuilding and other transportation equipment, lumber, food processing, metals and metal products, chemicals, and machinery.
The Okanogan Highlands and the rugged Kettle River Range and Selkirk Mountains cover much of the northeastern quadrant of the state.
The Palouse southeast region of Washington was grassland that has been mostly converted into farmland, and extends to the Blue Mountains.
This causes Washington's prevailing winds, the Chinooks, to come from the southwest, bringing relatively warm and moist air masses and a predictably wet season.
