Abstract
Long-range predictions of heat waves offer little improvement over climatology despite the continuing improvements of weather forecast models. Tropical variability in weather at sub-seasonal timescales is well-understood to influence weather in the Extratropics, particularly in the winter. For this reason, it is considered a potential source of sub-seasonal predictability of weather. However, much less is understood about the tropical-extratropical connection in the summer. we show that a major climate oscillation in the tropical west pacific is significantly correlated to U.S. heat waves with long lead times, suggesting potential for use in seasonal prediction of these events.
