METEOROLOGY – CLIMATOLOGICAL TATITIC & DATA CALCULATOR
Temperature Trend
A precise tool.
What is the Temperature Trend & How does it work?
The linear temperature trend is a measure of how the average temperature changes over time, typically expressed in degrees Celsius per decade (°C/decade). This metric helps climatologists understand long-term climate patterns and potential global warming effects.
T_{text{trend}} = frac{T_{text{end}} – T_{text{start}}}{(Y_{text{end}} – Y_{text{start}}) / 10}
Ttrend = Linear temperature trend (°C/decade)
Tend = Temperature at the end of the period
Tstart = Temperature at the start of the period
Yend = Year at the end of the period
Ystart = Year at the start of the period
Tend = Temperature at the end of the period
Tstart = Temperature at the start of the period
Yend = Year at the end of the period
Ystart = Year at the start of the period
To calculate the linear temperature trend, subtract the starting temperature from the ending temperature and divide by the number of decades between the two years.

Frequently Asked Questions
How do I calculate the linear temperature trend?
Use the formula T_trend = (T_end – T_start) / ((Y_end – Y_start) / 10), where T_end is the final temperature, T_start is the initial temperature, and Y_end and Y_start are the respective years.
What does a positive linear temperature trend indicate?
A positive linear temperature trend indicates that the average temperature is increasing over time, which could be a sign of global warming.
How do I interpret the units of the linear temperature trend?
The units of °C/decade indicate how many degrees Celsius the temperature increases or decreases on average each decade.
Can this calculator be used for any time period?
Yes, as long as you have the temperature data for the start and end of the period in question.
Why is the denominator divided by 10 in the formula?
Dividing by 10 converts the trend into degrees Celsius per decade, making it easier to understand long-term changes.
What if I only have temperature data for a few years?
You can still use this calculator, but keep in mind that shorter periods may not provide as accurate a representation of the overall trend.
