6. Next generation atmospheric model improves hurricane forecasting
Accurately predicting hurricane development from one season to the next is a problem that crosses multiple temporal and spatial scales. The driving force behind the overall activity level for a year depends on broad climate dynamics, such as the El NioSouthern Oscillation or the Madden-Julian Oscillation (MJO), while the generation of an individual tropical cyclone is a product of small-scale fluctuations in atmospheric moisture or sea surface temperature. Classically, these broad- or small-scale events have fallen within the realm of climate or weather forecasting models, respectively. However, researchers have recently developed the High-Resolution Atmospheric Model (HiRAM), which can flip between weather forecasting and climate modeling. HiRAM has 25-kilometer (15.5-mile) horizontal resolution and can properly represent clouds, both important improvements over current models.
Relying on HiRAM's ability to cross spatiotemporal scales, Chen and Lin retroactively predict the 2000 to 2010
