Also, cold air originating from Canada, warms rapidly over the ocean, forming thunderclouds. Thunderstorms, however, are very rare in Iceland, and there are less than five of them per year. [5] In June, Iceland's average daily temperatures range from 8 °C (46 °F) to 16 °C (61 °F). [9] Summer conditions vary in Norway depending on location ...
In many parts of the country, particularly in the interior and Prairie provinces, winters are long, very cold, and feature frequent snow. Most of Canada has a continental climate , which features a large annual range of temperatures, cold winters, and warm summers.
If the air mass is colder than the ground below it, it is labeled k. If the air mass is warmer than the ground below it, it is labeled w. [6] While air mass identification was originally used in weather forecasting during the 1950s, climatologists began to establish synoptic climatologies based on this idea in 1973. [7]
This is a list of countries and sovereign states by temperature. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1991 – 2020, from World Bank Group , derived from raw gridded climatologies from the Climatic Research Unit .
The system assigns a temperature subgroup for all groups other than those in the A group, indicated by the third letter for climates in B, C, D, and the second letter for climates in E. For example, Cfb indicates an oceanic climate with warm summers as indicated by the ending b. Climates are classified based on specific criteria unique to each ...
Continental climates exist where cold air masses infiltrate during the winter from shorter days and warm air masses form in summer under conditions of high sun and longer days. Places with continental climates are as a rule either far from any moderating effect of oceans or are so situated that prevailing winds tend to head offshore. [ 6 ]
Every month a polar climate has an average temperature of less than 10 °C (50 °F). Regions with a polar climate cover more than 20% of the Earth's area. Most of these regions are far from the equator and near the poles , and in this case, winter days are extremely short and summer days are extremely long (they could last for the entirety of ...
The warmest annual average temperature in Southwestern Finland is 6.5 °C (43.7 °F). From there the temperature decreases gradually towards north and east. The Suomenselkä and Maanselkä drainage divides rise higher than the surrounding areas, and the climate there is cooler than at same latitudes elsewhere in Finland. [4]
