(a) Daily Mean Temperature — The average of the maximum temperature and minimum temperature recorded during a day (24 hours) is known as daily mean temperature.
Daily Mean Temperature
=(Max.Tamp.+Min.Temp.)/2
For example, if a place has the maximum temperature of 39°C and minimum temperature of 27°C for a particular day, the daily mean temperature.
=(39°+27°) / 2 = 66°/2=33 °C
(b) Monthly Mean Temperature — The average of the daily mean temperature of all days of a month is known as monthly mean temperature. Monthly mean temperature of July
= (Daily mean temp.of 1+2+3....31days) / 31
(c) Annual Mean Temperature — The average of daily mean temperature of all days of a year is known as Annual mean temperature.
Annual mean temperature of year 2010
= (Daily mean temp.of 1+2+3....365days) / 365
(d) Mean Temperature of a place — Mean temperature of a place is obtained by collecting the data for a period of 30 – 40 years. The average of mean annual temperature of a place is calculated. This is also known as normal temperature of a place.
Mean temperature
(Mean Annual temp. of 1986 + 1985 ..........for 35 years) / 35
