Making up deficits
Posted: 05 Jul 2013 05:39 AM
Thanks to a wet spring and June, Iowa made up its 365 day precipitation
deficit from the drought of 2012. The featured chart presents some
metrics related to making up this year long precipitation deficit. The
top panel displays the daily rate the deficit was made up as measured
from the date with the largest deficit to when the deficit was erased.
The second panel displays the number of days it took for the given
deficit to be erased. The bottom panel displays the depth and time of
each period since 1900 with a deficit for statewide precipitation.
This year's deficit bottomed out at 9.18 inches on 26 Jan 2013 and was
erased on 24 June 2013 (red items on chart). The chart shows that once
the long term deficit reaches four or more inches, it will probably
take three months or more to recover.
