However, since climate models are better able to capture broad patterns of middle atmospheric pressure (which are strongly linked to precipitation) than precipitation itself, it's likely that we can still say something meaningful about trends in large - scale
atmospheric patterns conducive to low precipitation (and, therefore, drought).
Trends in
atmospheric patterns conducive to seasonal precipitation and temperature extremes in California
Human - caused climate change has increased the likelihood of extremely high atmospheric pressure over the North Pacific Ocean, which suggests an increased risk of
atmospheric patterns conducive to drought in California.
Not exact matches
The
atmospheric patterns were less
conducive to melt and (apparently) ice export than in 2007, so a new record was averted.
Such oscillations might also alter hurricane
patterns, but the main driver of hurricanes is warm sea surface temperatures > 27C (we can all agree on that, I hope);
atmospheric conditions also need to be
conducive (see the above comment on this year's rip - snorting season).
