Despite high level the aviation development, visibility (<strong>Meteorological</strong> Optical Range MOR)
remains a factor of great importance in all ordinary aircraft operations, both civil and military.
A pilots increasing interest in visibility (MOR) is explained by the fact that the MOR often
changes rapidly (particularly in radiation fog). There are 4 international aerodromes operating
in Lithuania, one of them military. Fog recurrence at these aerodromes is distributed unevenly
over the year. The situation varies during a day as well as over a very short period (from 1 to
30 min). This is because fogs are very sensitive to local influences. Both topography and
conditions on the ground are factors responsible for the local nature of many radiation fogs.
They may cover a large area, but usually are more localized*. And this amounts to a problem
for aeronautical forecasters in Lithuania - not merely to predict a MOR in their TREND and
TAF forecasts, but also to verify them following strict ICAO Annex 3 requirements an equally
important task. The objectives of this presentation are the following: To demonstrate and
evidence a jumpy changeability of the meteorological visibility during a very short period and
over a very limited area (on runways of the aerodromes of international airports in Lithuania)
To raise an issue of the verification of short-range aeronautical forecasts in accordance with
ICAO Annex 3, Attachment (unfortunately, these requirements are uniform for entire world,
though they should not) To present proposals concerning observations and their verification
for meteorologists consideration.

There are 8 operational weather radars in Cuba, so Cuban archipelago is well covered by
overlapping radars umbrellas. This fact suggested a new approach to deliver radar
information to forecasters in provincial centers. We made a WEB site presenting not
individual radar images, but Mosaics of overlapping radars. This way forecasters can stay
abstracted about which radar is working or not. Any available radar information over his
province will be WEB posted in the Mosaic of his province. Besides the Mosaics, forecasters
have comments from at least two radar operators about his province Mosaic. This new way of
presenting radar information has demonstrated to be very usefull in local forecast.
