Exploring NWS forecasters' assessment of AI guidance trustworthiness
As artificial intelligence (AI) methods are increasingly used to develop new guidance intended for operational use by forecasters, it is critical to evaluate whether forecasters...- publication PDF

Jet alignment in a two-layer quasigeostrophic channel using one-dimensional...
Because of position errors traditional methods of data assimilation can broaden and weaken jets or other flow structures leading to reduced forecast skill. Here a technique to...- publication PDF
