    This page lists notable bicycle brands and manufacturing companies past and present. For bicycle parts, see List of bicycle part manufacturing companies.. Many bicycle brands do not manufacture their own product, but rather import and re-brand bikes manufactured by others (e.g., Nishiki), sometimes designing the bike, specifying the equipment, and providing quality control.

  3. Wind wave model - Wikipedia

    en.wikipedia.org/wiki/Wind_wave_model

    The output of a wind wave model is a description of the wave spectra, with amplitudes associated with each frequency and propagation direction. Results are typically summarized by the significant wave height, which is the average height of the one-third largest waves, and the period and propagation direction of the dominant wave.

  4. Wind wave - Wikipedia

    en.wikipedia.org/wiki/Wind_wave

    In fluid dynamics, a wind wave, or wind-generated water wave, is a surface wave that occurs on the free surface of bodies of water as a result of the wind blowing over the water's surface. The contact distance in the direction of the wind is known as the fetch. Waves in the oceans can travel thousands of kilometers before reaching land.

  5. Walker circulation - Wikipedia

    en.wikipedia.org/wiki/Walker_circulation

    The Walker circulation, also known as the Walker cell, is a conceptual model of the air flow in the tropics in the lower atmosphere (troposphere). According to this model, parcels of air follow a closed circulation in the zonal and vertical directions. This circulation, which is roughly consistent with observations, is caused by differences in ...

    Kona Bikes. Kona Bikes is a bicycle company based in the Pacific Northwest. The company was founded in 1988 by Dan Gerhard, Jacob Heilbron and Jimbo Holmstrom in Vancouver, BC. Their world headquarters are in Ferndale, Washington, with Canadian distribution offices in Vancouver, and European distribution offices in Monaco. [2][needs update]

  7. Cyclic model - Wikipedia

    en.wikipedia.org/wiki/Cyclic_Model

    A cyclic model (or oscillating model) is any of several cosmological models in which the universe follows infinite, or indefinite, self-sustaining cycles. For example, the oscillating universe theory briefly considered by Albert Einstein in 1930 theorized a universe following an eternal series of oscillations, each beginning with a Big Bang and ending with a Big Crunch; in the interim, the ...

  8. Milankovitch cycles - Wikipedia

    en.wikipedia.org/wiki/Milankovitch_cycles

    Vostok ice core (Antarctica) Vertical gray line shows present (2000 CE) Milankovitch cycles describe the collective effects of changes in the Earth's movements on its climate over thousands of years. The term was coined and named after the Serbian geophysicist and astronomer Milutin Milanković.

  9. Wind-wave dissipation - Wikipedia

    en.wikipedia.org/wiki/Wind-wave_dissipation

    Wind-wave dissipation or "swell dissipation" is process in which a wave generated via a weather system loses its mechanical energy transferred from the atmosphere via wind. Wind waves, as their name suggests, are generated by wind transferring energy from the atmosphere to the ocean's surface, capillary gravity waves play an essential role in ...
