  2. Gulf Stream - Wikipedia

    en.wikipedia.org/wiki/Gulf_Stream

    Surface temperatures in the western North Atlantic: Most of the North American landmass is black and dark blue (cold), while the Gulf Stream is red (warm). Source: NASA The Gulf Stream is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and flows through the Straits of Florida and up the eastern coastline of the United States, then veers east near 36°N latitude ...

  3. Clear-air turbulence - Wikipedia

    en.wikipedia.org/wiki/Clear-air_turbulence

    In meteorology, clear-air turbulence (CAT) is the turbulent movement of air masses in the absence of any visual clues, such as clouds, and is caused when bodies of air moving at widely different speeds meet.

  4. Geostrophic current - Wikipedia

    en.wikipedia.org/wiki/Geostrophic_current

    A geostrophic current is an oceanic current in which the pressure gradient force is balanced by the Coriolis effect. The direction of geostrophic flow is parallel to the isobars , with the high pressure to the right of the flow in the Northern Hemisphere , and the high pressure to the left in the Southern Hemisphere .

  5. Ocean current - Wikipedia

    en.wikipedia.org/wiki/Ocean_current

    The largest ocean current is the Antarctic Circumpolar Current (ACC), a wind-driven current which flows clockwise uninterrupted around Antarctica. The ACC connects all the ocean basins together, and also provides a link between the atmosphere and the deep ocean due to the way water upwells and downwells on either side of it.

  6. Thermohaline circulation - Wikipedia

    en.wikipedia.org/wiki/Thermohaline_circulation

    It combines direct estimates of ocean transport using current meters and subsea cable measurements with estimates of the geostrophic current from temperature and salinity measurements to provide continuous, full-depth, basin-wide estimates of the meridional overturning circulation. However, it has only been operating since 2004, which is too ...

    Recent studies Williams has worked on show severe turbulence is increasing by 149% increase versus 59% for light turbulence. However, severe turbulence will likely remain very rare.

  8. Jet stream - Wikipedia

    en.wikipedia.org/wiki/Jet_stream

    Clear-air turbulence can cause aircraft to plunge and so present a passenger safety hazard that has caused fatal accidents, such as the death of one passenger on United Airlines Flight 826 in 1997. [ 47 ] [ 48 ] Unusual wind speed in the jet stream in late February 2024 pushed commercial jets to excess of 800 mph (1,300 km/h; 700 kn) relative ...

  9. Atmospheric instability - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_instability

    The Bulk Richardson Number (BRN) is a dimensionless number relating vertical stability and vertical wind shear (generally, stability divided by shear). It represents the ratio of thermally-produced turbulence and turbulence generated by vertical shear. Practically, its value determines whether convection is free or forced.
