Meteorology

Flying weather: Frequent low cloud and fog formation, especially in winter and

spring. Rain and wind can also create turbulence, especially near coastal areas.

Good visibility in clear weather, but often unstable.

Polar climates are characterized by very cold temperatures - all months have

o
an average temperature below 10 C. Summers are short and cool, and winters
are long and cold.

There is little precipitation, which is distributed throughout the year. In the

southern part, the tundra, there are no trees, but only moss and lichen. In the

polar climate, only ice and snow fields are found.

Flying weather: Low temperatures can cause ice formation on aircraft and on

runways. Low temperatures can also affect engine performance. Poor visibility

in winter with dark periods, which makes accurate weather forecasts
important.

The continental climate of the coniferous forest has long, cold winters with an
o
average temperature below –3 C for the coldest month, warm summers with
o
at least 1 month with an average temperature above 10 C.

Precipitation is low to moderate and falls mostly as snow in winter and is very

variable due to frequent low-pressure passages.

Flying weather: Cold and heavy snow in winter can lead to ice formation on

aircraft and runways. Winds can create heavy snowdrifts, which reduce

visibility and can cause turbulence. Low temperatures also mean that flight
operations require special attention to ice and snow conditions.
