| has gloss | eng: The Saharan Air Layer (SAL) is an intensely dry, warm and sometimes dust-laden layer of the atmosphere which often overlays the cooler, more-humid surface air of the Atlantic Ocean. In the Sahara Desert region of North Africa, where it originates, it is the prevalent atmosphere, extending from the surface upwards several kilometers. As it drives, or is driven, out over the ocean, it is lifted above the denser marine air. This arrangement is an inversion where the temperature increases with height. The boundary between the SAL and the marine layer suppresses or "caps" any convection originating in the marine layer. Since it is dry air, the lapse rate within the SAL itself is steep, that is, the temperature falls rapidly with height. |

| has gloss | fin: Calina eli calima on kesäinen kuuman ilman pyörrevirta Keski-Espanjassa. Kohotessaan se vie mukanaan tomua ja aiheuttaa huonon näkyvyyden. Tavataan varsinkin Sevillan alueella. Sitä esiintyy myös pari kertaa vuodessa yleensä talvella Kanariansaarilla, jonne se puhaltaa etelästä tai kaakosta. Se syntyy korkeapaineen aikana Pohjois-Afrikan yläpuolella ja kulkeutuu kohti kylmää rintamaa Kanariansaarten pohjoispuolelle. Tuuli kuljettaa mukanaan tomua Pohjois-Afrikasta. |

| has gloss | nor: Calima er et værfenomen som innebærer het vind fra sør eller sørøst, og som forekommer over Kanariøyene et par ganger hvert år, oftest vintertid. Det oppstår ved et høytrykk over Nordafrika som drar ut mot en passerende kaldfront nord for Kanariøyene. Med vinden følger støv og sand fra de tørre områdene i Nordafrika, der vinden begynner. Calima fører til ekstremt høye temperaturer når den forekommer og gjør at lufta ser disaktig ut. |
