The span between the highest and lowest recorded temperatures for a given location over one year provides a significant indicator of climate variability. This value is derived by subtracting the year’s minimum temperature from its maximum temperature. For example, if a location experiences a high of 30C and a low of 5C within a calendar year, the resulting variance is 25C.
This temperature differential is crucial for understanding regional climate characteristics. A large temperature variation can suggest a continental climate, often associated with greater seasonal shifts. Conversely, a smaller range may indicate a maritime climate, typically exhibiting more stable temperatures due to the moderating influence of large bodies of water. Historically, analyzing these temperature differences has aided in agricultural planning, infrastructure development, and understanding long-term climatic trends.
