100,000 km 2 (39,000 sq mi) Cook Inlet (Tanaina: Tikahtnu; Sugpiaq: Cungaaciq) stretches 180 miles (290 km) from the Gulf of Alaska to Anchorage in south-central Alaska. [1] Cook Inlet branches into the Knik Arm and Turnagain Arm at its northern end, almost surrounding Anchorage. On its southern end, it merges with Shelikof Strait, Stevenson ...
The National Oceanic and Atmospheric Administration (abbreviated as NOAA / ˈ n oʊ. ə / NOH-ə) is a US scientific and regulatory agency charged with forecasting weather, monitoring oceanic and atmospheric conditions, charting the seas, conducting deep-sea exploration, and managing fishing and protection of marine mammals and endangered species in the US exclusive economic zone.
Coordinates: 60.9872°N 149.7947°W. Turnagain Arm from Anchorage. Turnagain Arm (Dena'ina: Tutl'uh) is a waterway into the northwestern part of the Gulf of Alaska. It is one of two narrow branches at the north end of Cook Inlet, the other being Knik Arm. Turnagain is subject to climate extremes and large tide ranges. [1]
Map of regions covered by the 122 Weather Forecast Offices. The National Weather Service operates 122 weather forecast offices. [1] [2] Each weather forecast office (WFO or NWSFO) has a geographic area of responsibility, also known as a county warning area, for issuing local public, marine, aviation, fire, and hydrology forecasts.
Tide table. Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a ...
The first tide predicting machine (TPM) was built in 1872 by the Légé Engineering Company. [11] A model of it was exhibited at the British Association meeting in 1873 [12] (for computing 8 tidal components), followed in 1875-76 by a machine on a slightly larger scale (for computing 10 tidal components), was designed by Sir William Thomson (who later became Lord Kelvin).

Climate change. Based on the ERA5 data published by ECMWF, the annual mean temperature of Anchorage has increased from 0.8 °C in 1940 to 3.8 °C in 2022, an increase of 3 °C. [8] The mayor and the assembly of Anchorage in 2019 issued a climate action plan for the anticipated effects that climate change will have on its city and people. [9]
The theory of tides is the application of continuum mechanics to interpret and predict the tidal deformations of planetary and satellite bodies and their atmospheres and oceans (especially Earth's oceans) under the gravitational loading of another astronomical body or bodies (especially the Moon and Sun).
