A jetlike northward looping excursion of the Antarctic Circumpolar Current east of southern Argentina; also known as the Falkland Current. Somewhere between 33° and 38°S it meets the Brazil Current and turns eastward, forming an intense temperature and salinity front.

A wind, named after the Maloja Pass between the Engadine and Bergall, Switzerland, that blows down the valley of the Upper Engadine by day and either up or down by night. This deviation from the usual nature of mountain and valley winds is attributed to the fact that the stronger daytime valley wind from the south overtops the ridge and continues down the Engadine.

A quasiperiodic oscillation of the near-equatorial troposphere, most noticeable in the zonal wind component in the boundary layer and in the upper troposphere, particularly over the Indian Ocean and the western equatorial Pacific. This phenomenon is named after the codiscoverers. The oscillation can be detected globally in winds near the tropopause. The period of the oscillation varies between about 30 and 50 days, and appears to represent an eastward-propagating disturbance with the structure of a Kelvin wave with a vertical half-wavelength of the depth of the troposphere, but with a phase speed of only about 8 m s<sup>−1</sup>, much less than that of an adiabatic Kelvin wave. The disturbance is accompanied by strong fluctuations of deep convection, easily detectable using satellite observations, and is a major contributor to intraseasonal weather variability in equatorial regions from eastern Africa eastward to the central Pacific.
