Oct 2014 Southwest Climate Podcast: Monsoon Recap & El Niño Double Dips?

Friday, October 24, 2014

In the October Southwest Climate Podcast, CLIMAS climate scientists Zack Guido and Mike Crimmins discuss the 2014 monsoon, focusing on the influence of tropical storm systems, record and near-record precipitation events, monsoon intensity and duration, and the ever-present promise of El Niño.  (read more)

Monsoon Recap - June 15 - Sept 30, 2014

Friday, October 17, 2014

Looking back on the 2014 monsoon, a simple characterization of the season as ‘normal’ or ‘average’ (or above or below these thresholds) is difficult, given the spatial and temporal variability of monsoon storms. The cumulative seasonal totals provide one way of characterizing the monsoon, and by those metrics, the Southwest saw an average to above-average summer rainy season, with much of Arizona and New Mexico receiving well above-average rainfall.

2014/2015 El Niño Tracker: Oct 16, 2014

Thursday, October 16, 2014

An El Niño Watch, issued by the NOAA Climate Prediction Center (CPC), continues for the seventh consecutive month as signs of an emerging El Niño are just on the horizon, but not quite here yet. Another slug of warm water (also known as a Kelvin wave), has been making its way across the Pacific Ocean from west to east just below the surface and is poised to emerge and help warm sea surface temperatures in the eastern Pacific over the next month or so...(read more)

Notes from an Applied Climatologist - Sept 2014 Rainlog Climate Summary

Friday, October 3, 2014

September turned out to be quite a month as far as extreme monsoon season weather across Arizona. The month started out rather quiet as the monsoon ridge of high pressure weakened and a trough of low pressure to the north ushered in dry air from the west across the state. This suppressed thunderstorm activity for several days until the monsoon ridge pushed back north helping to bring low level moisture back into the region.  (read more)

Monsoon Summary (June 15 – Sep 18)

Friday, September 19, 2014

We are nearing the end of the 2014 season, and while it is difficult to characterize the highly variable day-to-day storms of any monsoon as “normal,” we have had a fairly typical if not above-average monsoon season in terms of precipitation. Regional assessment is complicated by the effects of a few extreme events that amplified precipitation amounts in parts of Arizona and New Mexico and caused an entire month’s or year’s worth of precipitation to fall in a single storm.
