Humid continental climateA humid continental climate is a climatic region defined by Russo-German climatologist Wladimir Köppen in 1900, typified by four distinct seasons and large seasonal temperature differences, with warm to hot (and often humid) summers and cold (sometimes severely cold in the northern areas) winters. Precipitation is usually distributed throughout the year but often does have dry seasons. The definition of this climate regarding temperature is as follows: the mean temperature of the coldest month must be below or depending on the isotherm, and there must be at least four months whose mean temperatures are at or above .
Climat méditerranéenLe climat méditerranéen, selon la classification de Köppen (Csa et Csb), est un climat tempéré (également appelé « tempéré chaud » ou « subtropical de façade ouest », selon les considérations), qui se caractérise par des étés chauds et secs et des hivers doux et humides. Le terme de « méditerranéen » s'explique par sa présence caractéristique autour de la mer Méditerranée, mais d'autres régions du monde possèdent les mêmes conditions climatiques.
Diurnal air temperature variationIn meteorology, diurnal temperature variation is the variation between a high air temperature and a low temperature that occurs during the same day. Temperature lag, also known as thermal inertia, is an important factor in diurnal temperature variation. Peak daily temperature generally occurs after noon, as air keeps absorbing net heat for some period of time after noon. Similarly minimum daily temperature generally occurs substantially after midnight, indeed occurring during early morning in the hour around dawn, since heat is lost all night long.
