How have extratropical, large-scale waves evolved over the past
several days in the Northern Hemisphere (NH) and Southern Hemisphere
(SH)?
More specifically, what wave number(s) have been prominent and
how have they moved?
Have there been any prominent stationary features in the waves?
How has overall wave evolution played a role in our recent
weather?
(b) Forecasted behavior
What are the forecasted movements of troughs and ridges
associated with these waves?
What weather changes may be expected over the next couple of days
in a Southern Hemisphere region (e.g., southern South America, South
Africa, Australia, Antarctica)?
How do forecasts from different sources compare?
(c) Related behavior
Where are the maxima in the zonal average zonal wind in both the
NH and SH?
How have the maxima evolved over the past few days?
What are the differences between the NH and SH?
How have the maxima been evolving since the start of the course?
(d) Raising additional points beyond these will produce extra credit.
