How are these Temperatures Measured?
Generally, temperature data depicting climate is usually given over a 30-year average in order to reduce short-term fluctuations and reveal better long-term trends in climate conditions.
This temperature data is taken from land-based thermometers, ocean buoys, ships, and satellites. These measurements are transmitted to weather stations and climate centers around the globe where they are processed, averaged, and analyzed in order to monitor the trends and create climate models.
Effects of Temperature on Weather and Climate
Temperature variations influence precipitation patterns in Amsterdam:
Rainfall: Warm air holds more moisture, leading to heavier rain during warmer months. However, precipitation is generally moderate year-round.
Snow: Occasional snowfall occurs in winter, though it rarely lasts very long.
