Advection of warm moist air over a cooler surface, such as water, causes fog.


1. The transfer of a property of the atmosphere, such as heat, cold, or humidity, by the horizontal movement of an air mass: Today's temperatures were higher due to the advection of warm air into the region.
2. The rate of change of an atmospheric property caused by the horizontal movement of air.
3. The horizontal movement of water, as in an ocean current.

[Latin advectiō, advectiōn-, act of conveying, from advectus, past participle of advehere, to carry to : ad-, ad- + vehere, to carry; see wegh- in Indo-European roots.]

In its 24-hour outlook, the Meteorological Department of Oman said: "Mainly clear skies over most of the Sultanate with chances of cloud development over Al Hajar Mountains towards Wednesday afternoon and chances of clouds advection over Dhofar governorate." The sea will be moderate along the Arabian sea coasts with maximum wave height of 2 metres and along Oman coasts with maximum wave height of 1.5 metres.
Upper-air maps representing 850, 500, and 300 hPa included instructions to annotate troughs and ridges, shade areas of cold and warm air advection (CAA/ WAA), positive (cyclonic) and negative (anticyclonic) vorticity advection (PVA/NVA), and divergence and convergence.
The Directorate General of Meteorology in its forecast for May 16 and 17 stated that clear skies were expected over most of the sultanate with advection of high and medium clouds.
Moreover, their implementation used a Semi-Lagrangian advection model.
The atmosphere is relatively stable here, but this can be a good setup for bands of moderate to heavy snow and sleet, which meteorologists sometimes identify as being caused by something called "slantwise convection." It's far too technical to describe here, but we occasionally see it within warm advection patterns where there is strong forcing.
The phenomenon on Friday was advection fog, when hot air from the land hits cooler air over the sea.

After explaining its basic properties, they describe its use in explicit Runte-Kutta methods, linear multi-step and predictor-corrector methods, some implicit methods, splitting techniques, advection problems, and other problems.
Visual foresight is based on 'convolutional recurrent video prediction,' or dynamic neural advection (DNA).
Over North America during winter and spring, the most frequent northerly advection (occurring on about one-fifth of days) was underestimated in all three model integrations, in which the frequency of the northern circulation type varied between 15% and 17% (Figure 6(a)).
