Possible tropical sources of predictability for inter- annual variability of summer precipitation over Nordic European countries

We analyse the inter-annual variability of summer precipitation over Nordic European countries, focused particularly on Sweden and Finland, and its connection to global variability. After finding a link between summer precipitation over Nordic European countries and tropical and subtropical variability over the Pacific and the Caribbean during early spring, we show the potential predictability of summer precipitation over Nordic European countries based on a multi-linear regression model.
