Also, the IFS cannot resolve the sharp potential vorticity (PV) gradient across the jet stream and tropopause, and this PV gradient weakens with forecast lead time. Cases with larger wind biases are characterized by higher PV biases and PV biases tend to be larger for cases with a higher ...
What we often see with La Niña, and the orientation of the jet stream, is that it lends itself naturally to northwest flow setups. This can bring significant snowfall out West, often in regions like the Tetons and Western Colorado. It can also bring significant snowfall to Utah’s Wasatc...
By using the durative rainstorm data in the South China during May-early June in 2010,the forecast characteristics of K index and low-altitude jet stream w... MA Xiao-Gang - 《Journal of Anhui Agricultural Sciences》 被引量: 4发表: 2010年 Analysis of the Process and Results of High-Press...
This east–west mountain orientation is uncommon in the North American Cordillera, so was purposefully removed. The southern dipole model, referred to as the South–Sonora model was drawn as a parallelogram to mimic the area of ENSO impacts along the Sierra Madre Occidental mountains. This region...
The U.S. Southwest relies on the increasingly erratic seasonal phenomenon to help fight wildfires and drought. Now researchers are getting better at predicting it.
a powerful jet stream trough will dig over the Rockies and eject energy over the central and southern plains by midweek. Models have been slightly more progressive in trends, leading to a late Tuesday into Wednesday morning arrival for activity in North Texas. We shall see. Either way, exp...
A band of intense rainfall extends more than 1,000 km along Mexico’s west coast during Northern Hemisphere summer, constituting the core of the North American monsoon1,2. As in other tropical monsoons, this rainfall maximum is commonly thought to be
These results have implications for models and types of analysesused to dynamically forecast rainfallsbrought by the North American monsoon in the region, especially consideringthe consequences that climate change could havein terms of droughts or extreme weather events. ...
In the extra-tropics, warm SSTAs persist in the North Pacific and Atlantic Oceans, alongside cold SSTAs along the North American coast during the CV and HW stages. The extra-tropical SSTAs act as responses to anomalies of atmospheric circulation41,42. Fig. 8: Influences of SSTA on Indian ...
