This positive trend in Greenland summer blocking is likely responsible for downstream troughing and relatively normal to cool temperatures across Northwestern Europe including the UK seen in Figure i. Currently Greenland is dominated by deep troughing / relatively
low geopotential heights.

* Extremely high
geopotential heights (a vertically aggregated measure of atmospheric temperature) over the northeastern Pacific Ocean are historically linked to very
low precipitation in California.
The projection of 500mb
geopotential height (see Figure 10) for the remainder of July continues the June - to - early July SLP pattern (see Figure 9) with support for
low SLP over the Pacific Arctic.
The model's response agrees with observations, including the long record of
geopotential height variations (a function of temperature throughout the
lower atmosphere), implying that these observed 10 - 12 year oscillations are likely driven, at least partially, by solar variability.
