lämpötilapoikkeamien

Lämpötilapoikkeama refers to the deviation of observed temperatures from a long-term average or a reference period. This concept is crucial in climate science for understanding and monitoring climate change. When scientists discuss temperature anomalies, they are not necessarily referring to extreme weather events, but rather to the difference between the temperature recorded at a specific time and place, and the expected temperature for that location and time based on historical data.

These anomalies can be positive, indicating that the temperature is warmer than average, or negative, meaning it is colder than average. The reference period used for calculating anomalies is important and can vary, but it is typically a period of 30 years or more, chosen to represent a stable climate baseline. Analyzing temperature anomalies over time allows researchers to identify trends, such as the overall warming trend observed globally in recent decades.

Lämpötilapoikkeama data is collected from a vast network of weather stations, buoys, and satellites around the world. These measurements are then processed and averaged to create global or regional temperature anomaly maps and time series. Understanding these deviations is essential for assessing the magnitude and spatial patterns of climate change, predicting future climate scenarios, and informing policy decisions related to mitigation and adaptation strategies.
