Am trying to look for an equation or modei that can can connect the various or most of the  weather parameters

If you need regression equation, get local weather conditions data, such as temperature, wind speed, wind direction, relative humidity, atmospheric pressure etc and enter these into a multiple linear regression model, you will get the equation. Choice of model depends on the type of data and requirement of the study i.e. what you want from the study. There are many types of models that you can use. 

@Said thanks alot, please can you be of assistance in this regard. How will I get the multiple linear regression model? I will be glad to hear from you. ([email protected]).

Dear Kingsley, 

No problem, I will be glad to help. 

If you have a dataset send me the dataset and I shall make the model for you. If you send me your data, I will divide it to a training dataset (used to train the model) and a testing dataset (used to test the model i.e. to check the model performance on). 

I am using R for data analysis, do you prefer to use any other software?

Thanks

Dear Said, please i will appreciate if assist & possibly teach me the modeling using the required software. Please let communicate via email ([email protected]).
