BURA
Strong, sudden, dry, cold and sometimes hurricane strength wind (up to 12
on the Beaufort scale).
Blows in strong gusts from cold mountainous regions of east Adriatic coastline
often from NNE
to ENE direction. Configuration of the land creates both the direction and
intensity of the wind.
Bura savagely crushes on the sea surface and creates short, irregular, steep
and mostly low
waves (1-2,5m). Strong Bura blows away the crest of the waves and creates
a thick vapour from
small particles of saltwater that can reduce visibility thus cause shipwrecking
and is also dangerous
for people because it can be difficult to breathe since the vapour can easily
be inhaled.
The temperature of the air can plummet in a very short period of time for
over ten degrees.
The air pressure usually rapidly rises. Bura blows more often, stronger
and for longer in wintertime
(3-7 days), it is rare, weak and short in summer (2 days). As you get farther
from land, Bura gets
weaker and with less gusts but the waves get much bigger. Sudden appearance
of the bura is one
of her most dangerous characteristics. Cyclonic, "dark" bura is
very strong and constant wind
without gusts, blows from direction NE-E. It is followed by dark, cloudy,
rainy weather.
In winter often accompanied by sleet, sudden pressure and temperature fall.
TRAMONTANA
Pronounced TRAp-MONTANA
It's a more benign type of Bura. Blows from north. It is local, cold and dry,
short-term wind
(usually one day), but not so strong (9Bf) and gustily as bura.It is followed
with sunny weather
and high pressure, the further from the coast the stronger it gets and the waves
get higher.
It is stronger in the south parts of the Adriatic.
LEVANAT
Pronounced LExus-WAtt-ghaNA-raT
Eastern wind, short-termed, blows steadily, without gusts (7Bf). It is a wind
which blows
during transition when jugo changes to bura or vice versa. In winter it is often
followed
by rainy weather, low temperatures sometimes even snow. In summer during sunny
and stable
weather sometimes it blows in the early morning through channels in between
the
mid-Dalmatian islands.
JUGO - OSTRO
Southeastern wind, warm, damp, blows steady in both the direction and strength,
and without
gusts. Blows most frequent from the east-south-east direction (Jugo-Levanat),
south-east
(Jugo-Sirocco) and south (Oštro) direction. It builds up wind speed gradually
and can get
hurricane strong after 2-3 days. It blows more often and stronger on the east
than on the north
Adriatic coast. It blows strong on the open sea, but nearing the coast it gets
weaker.Cyclonic
"dark" Jugo is specific for its thick, dark gray, low and heavy clouds
pouring rain non-stop,
followed by thunders. Sometimes blows in gusts.Air pressure is low and stirred
sea interferes
with visibility. Other type of jugo blows on sunny and clear weather with little
or no clouds.
It appears more often in spring and autumn periods. High tide and rise of atmospheric
pressure
are its characteristics.
LEBIC (garbin)
Pronounced LEg-BITCH
Stormy wind (12Bf) that blows from the south-western direction, carrying showers,
creating
huge waves and lack of visibility. Particularly strong during winter and autumn,
and because
of its huge waves and sudden appearing it is dangerous for unprepared and unprotected
boats.
PULENAT
PULl-ENter-ATmosphere
Western wind. Rare, transient, short-termed, cold and dangerous, can be strong
up to 12Bf.
Brings short but abundant rain.
MAESTRAL
Northwest daily thermal wind typical for the summer period. Pleasant and fresh,
weak to
medium in intensity (6Bf). It is a friend of nice and sunny weather, mitigates
the summer heat,
brings low pressure. It blows very steady so it is particularly suitable and
pleasant for windsurfers.
It blows stronger and more often in south parts of the Adriatic coast. From
morning till sunset
it changes direction from east to northwest (it follows the sun) creating tall
and regular waves.
BURIN
Thermal opposite of Maestral that blows in summer nights after sunset from the
continent
towards the sea. Usually lasts whole night and can be mistaken with bura, because
of it's strength.
It can blow as far as 15 nm out to open sea. Its direction on the south Adriatic
coast is towards east.
Brings nice weather and high pressure.
SIGNS OF BED WEATHER
· sudden drop in atmospheric pressure
· extremely high tides
· absence of Maestral during summer, or if it unusually stops before
the usual time
· pale moon with wreath or aura around it foretells the weather change.
· red sky in the morning or rainbow early in the morning can announce
rain
· strong wind in the morning, during nice weather
· Maestral like wind during the winter often foretells Jugo and rain
· if bura changes direction to east, especially south-east
· gray cloud wall on west, especially in early evening
· pale-yellow colored sun right before sunset
· wreath or aura around the sun and moist wind blowing simultaneously
· constant low pressure during bad weather tells us that it will probably
last for long.
SIGNS OF NICE WEATHER
· progressive air pressure rising (especially above 1012 hPa)
· during cloudy day, appearance of clear sky on the western horizon
· in principle the wind after rain brings nice weather
· sky tinted red just after sunset when clouded
SIGNS OF PROLONGED NICE
WEATHER
· Maestral during the day, Burin until down
· extremely low tides, clear sky and no wind
· if during nice weather the sunset is clear and colorful
· no change in high pressure
· while Bura blows the weather cannot worsen |
