surface temperature (monthly data)
a) Calculate the surface temperature anomaly. The anomaly is achieved by subtracting the annual cycle from the t2m data.Annual cycle: average of the same month of each year.
b) Extract the December&January&February(DJF)
c) Calculate the average values of South-east of CHINA (20º-40ºN, 100-125ºE) -
nino3.4 index
extract the DJF month from the original data -
basic.py some functions dealing with the climatology data including: a) date processing b) calculate the anomalies by removing the annual cycle.
