Annual mean temperature refers to the average temperature over a year for a specific location. It is calculated by taking the average daily or monthly temperature readings throughout the year. The measurement is typically expressed in degrees Celsius (°C), although Fahrenheit (°F) is also used in some countries. On the other hand, seasonal mean temperature refers to the average temperature during specific seasons, such as winter, spring, summer, and autumn. In climates with well-defined seasons, these measurements can vary significantly, reflecting the natural changes in temperature throughout the year. Both annual and seasonal mean temperatures are essential metrics in meteorology and climate science, providing insight into the long-term climate patterns and variability of a region. They are derived from daily temperature observations collected at weather stations and analyzed to understand temperature trends over time.
