Arezzo is an Italian town of 98 969 inhabitants, the capital of the province of the same name in Tuscany. It was the seat of the oldest university in Tuscany, and one of the first in Europe.
The city of Arezzo is located in the northern part
of the Valdichiana; the two streams that cross it, the Castro and
the Vingone, flow into the Canale Maestro della Chiana, which traces
the bed of the ancient Clanis river. Directly north of the city
begins the Casentino, which is the valley crossed by the first
stretch of the Arno; to the north-west is the upper Valdarno, always
crossed by the Arno in the stretch between Arezzo and Florence.
Through the easy Torrino pass, the Cerfone valley and the Scheggia
pass you have access to the north-east to the fourth valley, the
Valtiberina, crossed by the first stretch of the Tiber.
The
territory of the municipality is very wide and varied: it passes
from the plain of the Val di Chiana to the hills, south of the city,
and mountainous areas, especially to the east. As a consequence of
the large extension of the municipal territory, the neighboring
municipalities are numerous: to the west and south are Civitella in
Val di Chiana, Monte San Savino, Marciano della Chiana, Castiglion
Fiorentino and Cortona; to the north-west still Civitella in Val di
Chiana, Laterina and Castiglion Fibocchi; to the north-east Capolona
and Subbiano; to the east Anghiari, Monterchi and the two Umbrian
municipalities of Città di Castello and Monte Santa Maria Tiberina
(Tuscan until 1927).
The climate of the city of
Arezzo and the surrounding areas has the most accentuated
continental characteristics of all of Tuscany, given the position
between the Valdarno and the Val di Chiana with the Apennine ridge
in the relative vicinity.
According to the classification of
climates of Köppen, the climate of the city of Arezzo belongs to the
Cfa group (humid subtropical climate), although according to some,
given the extreme proximity of the Apennines borderline with the
climate of the Cfb group (oceanic climate) as the average
temperature of the hottest month is only slightly above 22 ° C (22.1
° C according to the 1971-2000 average). Precipitation is irregular,
because the area can be influenced by both Atlantic wet currents and
continental dry currents coming from the north and east.
The
temperature range is high in both daily and annual values. Snow in
winter is not rare and the historical average is around 20 cm per
year, but between 2001 and 2012 the average annual accumulation
dropped to 8.25 cm based on the measurements made at the
meteorological station of the Air Force.
