SONOMA TECHNOLOGY

We are currently recruiting for several positions at Sonoma Technology, Inc.
(STI).

We are currently working on some very exciting projects; here are some examples:

Air Quality Forecasting and Public Outreach. STI meteorologists issue daily weather and air quality forecasts for over a dozen cities across the U.S.  These forecasts are disseminated to air quality agency websites and local and national media. STI meteorologists also develop forecast tools and provide forecast training to agencies worldwide.

Working with the U.S. EPA to Expand AirNow-International.
AirNow-International is a suite of state-of-the-art software programs based on the highly successful AirNow program (http://www.airnow.gov/). AirNow-I facilitates air quality management and promotes public awareness of air quality issues. The first implementation of the system was completed for Shanghai, China, in advance of the 2010 World Expo<https://www.youtube.com/watch?v=joljzDtA7FA>. It has since been expanded to other parts of China and Mexico.

Weather Research for Wind Energy. STI scientists are working with U.C. Davis to improve meteorological forecasts to support real-time wind energy production decisions. As part of this project, STI staff have deployed and are now operating instruments (sodars, ceilometers, radar wind profilers, and microwave radiometers) to continuously measure meteorology in the lower troposphere. Data from these instruments will be used to improve the physical parameterizations in the weather forecast models and improve initial conditions for input into the model.

Air Sensor Monitoring Program for Kids. STI is developing the Kids Making Sense<http://www.kidsmakingsense.org/> program, which enables youth to perform air quality measurements and empowers them to drive positive change in their communities.

I look forward to any questions or comments you may have about our company, projects, and staff.

Is this storm El Niño? Or is it the next one?


Is this storm El Niño?

Yes and No! Every storm from now through winter and into spring is to some degree being influenced by El Niño. The conditions that define this strong El Niño are already in place across the eastern tropical Pacific. There are some winter weather patterns that are influenced more by this and thought of as more "typical" of El Niño, but even a cold front from the Gulf of Alaska is to some extent being impacted. The same can be said for every storm being influenced by the fact it is winter, with the tilt of the earth and its position relative to the sun being different than in summer! 



Consequently, there is no way to look at one storm (or any other weather event) and say it is or is not because of El Niño. We get storms every winter anyway and there is no DNA test to say that it is only happening because of El Niño.

Which El Niño Index is Best?

Which El Niño Index is Best?

 

A Plethora of El Niño Indices

The November monthly Sea Surface Temperature Anomaly (SSTA) in Niño 3.4 region was a record +2.35, while the 3-month Oceanic Niño Index (ONI) for September-October-November is +2.04, second to a +2.18 for the same period in 1997.  So, is this the strongest El Niño on record or not? How about the monthly SSTA from December 1877 of +2.51?

In reality they are all correct as there is really no “best” metric. One may have elements that best describe a particular season in a particular location, while another may have the best teleconnection for a different time and place. 

A variety of different metrics are used to characterize El Niño; ranging from sea surface temperatures (SST) to sea-level pressure, surface winds, surface temperature and out-going longwave radiation. These are usually expressed in the form of an index; often in terms of the difference from long-term average (i.e., anomalies). Even indices based upon the same metric, like SST, may use different datasets, sampling periods (i.e., weekly, monthly, bi-monthly or tri-monthly) and/or different filtering techniques.

The Niño 3.4 region (map) has arguably the best teleconnections to seasonal weather in the United States and is widely used as a sampling area for SSTAs.

The Oceanic Niño Index (ONI), is the mostly widely used index in the United States to characterize El Niño events.  The ONI is the 3-month SST Anomaly (SSTA) for Niño 3.4 and calculated from moving 30-year average values. See http://ggweather.com/enso/oni.htm and http://www.cpc.noaa.gov/products/analysis_monitoring/ensostuff/ensoyears.shtml.

The Niño 3.4 region SST is also sampled on both a monthly (http://www.cpc.ncep.noaa.gov/data/indices/ersst4.nino.mth.81-10.ascii) and weekly (http://www.cpc.ncep.noaa.gov/data/indices/wksst8110.for) using the ERSST4 dataset back to 1950. There is also monthly Niño 3.4 data going all the way back to 1870 using the HadISST1 dataset  (http://icdc.zmaw.de/1/daten/ocean/hadisst1.html).

The Southern Oscillation, which was identified by British mathematician Sir Gilbert Walker in the early 1900s, is a periodic "see-saw" of pressure patterns in the tropical Pacific. This pattern was later linked to occurrences of El Niño and is the SO part of the combined acronym ENSO for El Niño Southern Oscillation. It is usually expressesed as the standardized Southern Oscillation Index (SOI). See https://www.ncdc.noaa.gov/teleconnections/enso/indicators/soi/.

The El Niño Modoki (translated from Japanese for "similar but different") Index quantifies ENSO events that are warmer in the central Pacific than the typical El Niño warming in the eastern Pacific. See http://www.jamstec.go.jp/frcgc/research/d1/iod/enmodoki_home_s.html.en.

And the Multivariate ENSO Index (MEI) brings together six different elements (sea-level pressure, zonal and meridional surface wind, sea surface temperature, surface air temperature and total cloudiness). See http://www.esrl.noaa.gov/psd/enso/mei/.

An excellent technical analysis of these various indices by Anthony Barnston of IRI can be found at https://www.climate.gov/news-features/blogs/enso/why-are-there-so-many-enso-indexes-instead-just-one.

All-Time Record Niño Region 3.4 Anomaly

All-Time Record Niño Region 3.4 Anomaly

 

The just updated Niño 3.4 region SST anomaly for November 2015 is +2.35.  This is the highest monthly SST anomaly (for any month) going back to the beginning of the dataset in 1950.  Previous the high was +2.33 in November 1997.

Monthly El Niño Analysis: Beware December!

Monthly El Niño Analysis: Beware December!

 

To date, much of the retrospective analysis of California rainfall during El Niño rainfall seasons has been looking at the teleconnections between seasonal totals and the strength of the El Niño events.  This analysis focused on monthly rainfall anomalies across California; and in doing so the biggest takeaway was that December during both strong and very strong events was historically drier than normal across most of the state north of the Tehachapis.

Would the amount of rain in the Carolina’s this past week be enough to end the California Drought? Not even close!

Would the amount of rain in the Carolina’s this past week be enough to end the California Drought? Not even close!

 

Several recent news reports have stated that the rain that fell over North and South Carolina this past week would be enough to erase the California drought. this was based on comparing an estimated 11 trillion gallons that the Carolinas received this past week to an amount from a NASA study that also used an 11 trillion gallon figure needed for California.  However the numbers don’t add up.

It’s been estimated that the average rainfall that fell across the Carolinas was 10.4 inches.  With a total area for North and South Carolina of about 85,000 square miles that actually equates to about 15.5 trillion gallons.  [Specifically 1” of water over 1 sq. mile= 17,378,560 gallons; times 10.4” of rain, times 85,839 sq. miles equals 15,514,285,403,136 gallons]

Now, looking at California. The statewide average rainfall for California is about 24 inches, and in round numbers the 4-year rainfall deficit is approximately a year’s worth of rainfall. Given the total California area of over 163,000 square miles that’s a phenomenal 68 trillion gallon deficit, or over four times the rain that fell on the Carolinas!  [Specifically 1” over 1 sq. mile= 17,378,560 gallons, times 24” of rain, times 163,694 sq. miles equals 68,274,384,015,360 gallons]

Some of the confusion arises from last December's NASA study that had a headline of "Needed: 11 Trillions Gallons to Replenish California Drought".  However, reading the entire article reveals the 11 trillion gallon amount was for only the Sacramento and San Joaquin river basins. And finally, it should be noted that to "end the drought" in some areas of California it may take more than a year's worth and in other areas less.

Update (10/9): Please note the rainfall amounts for California (above) are only to make up the deficit. To "end the drought" we would need to make up most of teh deficit, PLUS the normal rainfall of the winter of 2015-16, or another 24 inches.  Bottom line, we would be looking at as much 8 times the rains that flooded the Carolinas.

El Niño Circulation Reanalysis; September Summary; Worldwide AQI

El Niño Circulation Reanalysis; September Summary; Worldwide AQI

 

Here's a reanalysis of the 500 mb heights, height anomalies and the precipitable water anomalies for the strong and very strong El Niño winters (Nov-Mar). See http://ggweather.com/enso/reanalysis/ These really brought back my recollections from 1997-98 of the nearly continuous zonal flow across the Pacific, and the models being consistently too slow with the embedded short-waves.

~~~~~~~~~~~~~~~

Not surprisingly, September was warmer than normal statewide while precipitation ranged from negligible to epic (Los Angeles, 996% of normal). But the Southern California rainfall must be kept in perspective as normal in LA for September is on 0.24". See  http://ggweather.com/calif/sep2015.htm
