I said there would be twins! These two are (almost) identical twins, apart from the colour of their manes and tails. Everypony always get these two mixed up 'cause Summer is the pony on the left, while Winter is the pony on the right.
Both of them are meteorologists from Cloudsdale. They study all the different naturally occurring weather patterns around Equestria so they may attempt to find ways to manipulate the weather more efficiently and safely. They both take their job very seriously. f somepony told them a joke while they were working, it wouldn't matter if it were the funniest joke ever, they wouldn't even crack a smile. They would however laugh as soon as they finished working. Outside of work, they're just ordinary ponies. Go out, have fun, etc.
