The Relationship Between Temperature and the Latitude and Longitude

Research explores the correlation between temperature and latitude and longitude coordinates of 56 major U.S. cities from 1931 to 1960. Results show a strong negative linear association between temperature and latitude.

  1. The Relationship Between Temperature and the Latitude and Longitude By: Angela Couture Jaime Frade Rita Argelo

  2. Abstract • Question: Is there a relationship between temperature and global coordinates? Can latitude and longitude predict the temperature of that location? • Answer: After analysis, latitude is a strong predictor of the temperature.

  3. This study will concentrate on temperatures collected in the US from 1931 to 1960 • 56 major cities that spanned across the US were chosen • Each year, the daily min temp in January was tallied • A monthly average was computed for each city

  4. Data collection • Each city’s average temp was computed for the month of January • Each city’s coordinates were recorded

  5. Preliminary Analysis • Identify outliers in the data.

  10. Conclusion • The temperature and latitude for each U.S. city has a strong negative linear association. • In answer to our original research question, yes, it does appear that latitude is an adequate predictor of temperature in U.S. cities.
