Navigating the Seasons: Understanding Weather Patterns in Aeronautics and Finland

The concept of seasons in aeronautics is based on temperature changes, known as thermal seasons. These precise definitions help to outline the variations in weather throughout the year. For example, winter is characterized by temperatures mostly below zero, while spring begins when the average temperature rises above zero. Similarly, summer is marked by temperatures mostly above 10 degrees, and autumn arrives when temperatures drop below 10 degrees again.

The duration of each season can vary depending on the location. In Finland, for instance, summer lasts approximately 130 days on the southern coast, while winter spans around 110 days. In cities like Helsinki and Turku, summer is slightly longer than winter, but as you move further north, the length of winter increases while summer shortens. Tampere experiences roughly equal-length seasons, but most of Finland experiences a longer winter duration than summer.

In Lapland’s northern regions, summer lasts less than three months, with winter extending for half a year. This results in winter being twice as long as summer in these areas. The differences in season lengths across Finland highlight the diverse climate conditions experienced in different parts of the country.

Finally, it’s essential to note that these seasonal definitions are not universal and may vary depending on geographical location and altitude. Nonetheless, they provide valuable insights into how weather patterns change over time and help us better understand our environment.
