On the Annual Range of Temperature over the Globe
Published online by Cambridge University Press: 15 September 2014
Extract
The subject of range of temperature has been divided by meteorologists into the two main heads of Diurnal and Annual range, the former being measured by the variation of temperature between the warmest and coldest hours of the day, the latter by the difference of temperature between the warmest and coldest months of the year.
For a study of diurnal range we should require a series of observations for every hour of the day and night from all parts of the earth, and the places where such laborious observations have been made are as yet very few; but the returns of daily and monthly temperatures now obtainable from all countries are sufficient for a tolerably complete study of the simpler head of annual range.
