OK, first you need to load the dataset, and from data source properties window
do the spatial and time subset.
There will be a lot of clicks to select these time steps from June to August.
Second, Formula > Define a grid diagnostic, and select your display type, when
a window popup, enter
makeVector( averageOverTime(a), averageOverTime(b))
then a new popup will ask you to select a, b which should be U, V in your
dataset. That should create a display of what you want.
