Correlation between the weather indices.

Level of correlation	Positively correlated pairs of weather indices	Negatively correlated pairs of weather indices
Strong	Maximum relative humidity and minimum relative humidity, evaporation, and maximum temperature	Maximum temperature and minimum relative humidity, rainfall and maximum temperature, maximum relative humidity and maximum temperature, maximum relative humidity, and sunshine hours
Mediocre	Rainfall and minimum relative humidity, sunshine hours and maximum temperature, evaporation and evening wind, sunshine hours and evaporation, maximum relative humidity and morning wind, and maximum relative humidity and rainfall	Maximum relative humidity and evening wind, rainfall and evaporation, maximum relative humidity and evaporation, sunshine hours, and rainfall
