lämpötilasiirtymien

Lämpötilasiirtymä, often translated as temperature anomaly or temperature shift, refers to the deviation of the observed temperature from a reference average or baseline temperature. This baseline is typically calculated over a specific period, often 30 years, to represent a "normal" climate. For example, a lämpötilasiirtymä of +0.5°C means the observed temperature for a given period was 0.5 degrees Celsius warmer than the average for that period. Conversely, a negative lämpötilasiirtymä indicates a cooler-than-average temperature.

These anomalies are crucial in climate monitoring and research. They help scientists track changes in temperature over time and across different regions. By analyzing lämpötilasiirtymät, researchers can identify trends, such as the warming trend observed in global average temperatures over the past century, often referred to as global warming. The concept is applied to various scales, from local weather stations to global averages, and can be calculated for daily, monthly, seasonal, or annual periods.

Understanding lämpötilasiirtymät is essential for assessing the impacts of climate change, such as sea-level rise, extreme weather events, and changes in ecosystems. It allows for a standardized way to compare temperature conditions across different times and locations, providing a clear picture of how the climate is evolving.
