analysis and development 21 - 22 - 23 December 2010

Buonasera a tutti!!

Con l'inizio di questa settimana sull'Italia si cambierà nuovamente meteorological regime. An extended depression, generated by the last cold plunge further to the west of previous training is to the west of the European continent.

As shown in the first of the three images presented (source wetterzentrale.de), referring to the surface pressure and the geopotential at 500 h Pa, the minimum that will be deepened to 990 hPa on the Portuguese coast, will advance eastward within the circulation of the middle troposphere, pointing the area which best prepares his disposal, namely the Gulf of Liguria.
To anticipate the arrival of the minimum, there will be the usual call of sirocco winds a little over the whole Mediterranean area that, as shown in the second map of temperatures at 850 hPa (all maps are reported at 7 am Thursday local) will ensure a steady increase of temperatures. Already today the center-south has felt the change of air, while the north will be slower, because of difficulties in the way undermine the strong cold air cushion in the lower atmospheric layers. The two disturbances associated with depression will be extended bad weather, especially in the central north at first. Rising temperatures will be significant: at high altitude (850 hPa geopotential height, ie about 1400 m asl), where until a few days ago we had values \u200b\u200baround -10 ° C, will be spent in values \u200b\u200bbetween +2 and + 5 ° C al Nord, tra +5°C e +8°C al Centro, e tra +8° e +13° C circa al Sud nella giornata di giovedì. Gli effetti miti di questo aumento si vedranno presto anche al suolo.
I venti, come mostra la terza mappa, si disporranno da S-E un pò ovunque, solo sulla Liguria si avrà un pò di tramontana scura in un primo momento. Poi tra giovedì e Venerdì sarà possibile un forte libecciata prima, ed un ancor più intenso maestrale poi.
Le conseguenze ondose saranno buone un pò per tutte le coste, e come mostra l'ultima mappa LaMMa, la misura potrà essere anche di tutto rispetto. Si potrà tornare a surfare senza temere il freddo in costa west, and some also in the east coast, at least in terms of air temperatures. Well, Santa, if you will to change, will surely benefit in visiting us with a good longboard ...
