When the total lifetime of an extratropical cyclone over the ocean in the Northern Atlantic-region gets longer (within the same season): - Do the total precipitation sums increase? - Does the precipitation intensities increase? - Does the intensity of the cyclone increase? For example what would be the differences between a cyclone that lasts one or two days in total in winter versus a cyclone that lasts nine days in total in winter (both over water)? Any reliable research or research institution/organization that mention this/published research article mentioning/backing up this claim?
