Precipitation Events in December – An Overview of Storminess in Palermo, Italy
December is a chilly and wet month in Palermo, Italy, characterized by frequent precipitation events. These events are influenced by various factors, including orographic lift, wind patterns, and the Azores High. This section will delve into the relationship between the number of rainy days and average daily precipitation, as well as weather phenomena related to orographic lift and its effects on precipitation in the area.
Relationship between Rainy Days and Average Daily Precipitation
The number of rainy days and average daily precipitation in Palermo are closely linked. According to data from the National Institute of Statistics (ISTAT), Palermo experiences an average of 12 rainy days in December, with an average daily precipitation of 63 mm (24.9 inches). The frequency of rainy days increases as the month progresses, with 15 rainy days recorded in the last half of December. This is because the Azores High, a significant weather pattern, starts to weaken, allowing more moist air from the Mediterranean to reach the region.
Orographic Lift and Precipitation in Palermo, Palermo italy weather december
Orographic lift plays a crucial role in precipitation events in Palermo. The city is situated on the north coast of Sicily, where the land rises abruptly to the mountains. As moist air from the Mediterranean approaches the north coast, it is forced to rise, cool, and condense, resulting in precipitation. This phenomenon is more pronounced in December due to the prevailing northwesterly winds, which bring cold air from the Atlantic and force the moisture-laden air to rise and cool further.
Wind Patterns and Precipitation in Palermo
Wind patterns also influence precipitation events in Palermo. The Azores High, a persistent high-pressure system located in the northeastern Atlantic, plays a significant role in shaping the weather patterns in the Mediterranean, including Palermo. As the Azores High weakens in December, the northwest winds strengthen, bringing moist air from the Mediterranean and leading to increased precipitation.
