NORTH AFRICANA HIGH PRESION
Welcome back friends of RIWMAG and METEOEVENTI. Like clockwork, extreme variability that is featuring this crazy spring time will be with us this weekend.
This time it will dominate the high pressure north African that will station on the Mare Nostrum keeping away the perturbations coming from the Atlantic and coming to form what in meteorological jargon is called "blocking situation".
High pressure bumbazza ... "I rethink that doesn't mean so much real wind?”. No dear friends, the ground pressure will generally remain level and only some Italian coasts will enjoy some noteworthy ventilation, The others ... mostly thermal.
Pressure at high altitude (Geopotential Height 500 HPA in color) and on the ground (Black isoline) scheduled for the night between Saturday and Sunday. North African high-pressure headland highlighted, preventing Eastward movement of Atlantic perturbation (ECMWF data source www.tropicaltidbits.com www.ecmwf.int and processed by METEOEVENTI).
We give, then, a look into the future ... let's sum up, to date, what will be the situation of the winds on our coasts.
NORTH nothing to report. They will dominate thermals attenuated by high pressure.
Nothing to report CENTER. Here, too, the thermals will try to work in contrast to the high African pressure.
SOUTH High pressure also in southern Italy, so only thermal in view. The coasts where you will have the most chances will be those of Puglia of Salento (10/12 nodes) and, early in the morning, those overlooking the Strait of Messina (15 knots in sharp decline already in the morning).
ISOLE In Sardinia, bonifacio's mouths will be ventilated with winds of Levante up to 18/20 nodes, as well as the southwestern coasts of the island in the province of Carbonia for East-Southeast 20 nodes.
In Sicily we will have a ventilation from the North typical of the Strait, but limited to the hours of the morning.
NORTH The extreme west of Liguria may be reached by a foiled Levant (12/15 nodes). Thermal only on the remaining coasts of northern Italy.
Nothing to report CENTER. Even for Sunday, the thermals mitigated by high pressure from North Africa will dominate.
SOUTH Thermals also in the south. The most ventilated coasts will again be those salentine overlooking the canal of Otranto to Tramontana up to 15 nodes.
ISOLE In Sardinia will continue to blow the winds of Levante (20/22 nodes) bonifacio's mouths as far as Asinara (passing off the northern coast of Sardinian). The southwestern coasts of the island will also continue to enjoy mainly Levant winds on average on the 20 nodes, attenuation from late afternoon.
In Sicily only the westernmost coasts of Trapani will see a ventilation worthy of signalling (Scirocco up to 12/15 nodes).
