Cloud Seeding to Enhance Precipitation June 15, 2024

Global Warming and Population Growth, create a need for more Water.

There are a number of different ways to address a shortage of water:

  1. Get equal value from less water  (Conservation)

  2. Find more water from surface and groundwater  sources

  3. Have more precipitation (Increase the velocity of water)

In this article, we discuss “Finding More Water by Using Cloud Seeding to Increase Precipitation”.

Last Saturday we published an article based on a talk by Dr. Bruce M. Thomson, Regents Professor of Civil Engineering at the University of New Mexico. He gave a very good presentation on obtaining more water from brackish water, oilfield water, and importing water. You can access that article HERE.

Let us get started with today’s article on using cloud seeding to increase precipitation.

Weather modification with cloud seeding was discovered by General Electric at the Schenectady New York Laboratory.  Initially, on July 14, 1946, they used Dry Ice. Of course, prior to that time, there were other attempts at increasing precipitation

Cloud seeding can be used for three different purposes:  Precipitation enhancement, Hail suppression and fog dispersal.  In this article, I am focusing on precipitation enhancement.

…Multiple rounds of severe thunderstorms and locally heavy rain expected
to impact various locations in the northern and central U.S. through the
next couple of days…

…Late-season wet snow is forecast for the northern Rockies beginning on
Monday…

…A plume of tropical moisture is forecast to reach the central Gulf
Coast on Monday…

…A heat wave will quickly spread from the northern Plains this weekend
into the Great Lakes on Monday…

As a series of fronts pushes the showers and storms off the East Coast
early this morning, an active and changeable weather pattern will
establish across the Pacific Northwest. The unseasonably cold and
blustery conditions across this region will be in stark contrast with the
heat that is forecast to quickly spread from the northern Plains this
weekend, reaching into the Great Lakes on Monday. Areas in between these
temperature extremes will be under an active storm track where low
pressure systems will develop and move through in quick succession. The
first round of showers and storms associated with a leading system is
forecast to spark thunderstorm activity from the central Plains early this
morning to the upper Midwest by tonight. Multiple rounds of heavy rain
associated with these storms could lead to areas of flash flooding between
eastern Nebraska and northern Wisconsin. Additionally, a trailing and
stronger low pressure system is forecast to intensify and move quickly
across the northern Plains tonight. This system will help produce strong
to severe thunderstorms across parts of eastern Montana into North and
South Dakota. Unseasonably cold and windy weather will continue into
Sunday and Monday across the Northwest as yet another cold upper trough
reaches the Pacific Northwest. This system will reinforce the
unseasonably cold and windy conditions across the region on Monday along
with wet snow moving into the northern Rockies, therefore prompting the
issuance of Winter Storm Watches. Meanwhile, an area of rain and
thunderstorms is expected to develop and expand across the northern Plains
toward the upper Midwest where a stationary front strengthens ahead of a
developing low pressure system over the central High Plains.

Across the Florida Peninsula, the threat of heavy rain continues to
diminish as the main tropical moisture plume is forecast to swing farther
west and head toward the central Gulf Coast during the next couple of
days. Nevertheless, some thunderstorms that manage to develop over
southern Florida could result in local flooding issues given the already
saturated soil. By Monday morning, heavy rain associated with the
tropical moisture plume could begin impacting the central Gulf Coast
region. In contrast, a refreshingly dry airmass behind a cold front
should lead to beautiful weather this Father’s Day weekend throughout the
Northeast, Mid-Atlantic, and Ohio Valley.

The other main weather story this weekend will be the simmering heat
impacting areas from the Southwest to the Gulf Coast and Southeast. Highs
are forecast to reach the triple digits throughout much of the Desert
Southwest, with upper 90s stretching from the Southeast to parts of the
Southern Plains. Above average temperatures are also forecast across the
central Great Basin and northern Plains ahead of a cold front, with well
below average temperatures encompassing the Pacific Northwest. By Sunday,
an upper level ridge is anticipated to begin building across the Eastern
U.S., with anomalous heat starting in much of the Midwest, Central Plains,
and Tennessee Valley. Highs are forecast to reach the upper 90s, with
maximum heat indices near 105 degrees. When combined with warm overnight
lows, major heat risk could affect anyone without effective cooling and/or
adequate hydration. Be sure to remain weather aware and follow proper heat
safety!

NOAA Updates its ENSO Alert on June 13, 2024 – The El Nino Advisory/La Nina Watch Continues but it is expected to be the Final El Nino Advisory – Published June 14, 2024

On the second Thursday of every month, NOAA (really their Climate Prediction Center CPC) issues its analysis of the status of ENSO. This includes determining the Alert System Status.  NOAA now describes their conclusion as “ENSO Alert System Status: Final El Nino Advisory/ La Nino Watch”

The exact timing of the transition is now fairly clear which should increase the reliability of the Seasonal Outlook to be issued next Thursday.

We have included an ENSO Blog article by

>

CLIMATE PREDICTION CENTER ENSO DISCUSSION

 

The second paragraph is what is important:

“The most recent IRI plume indicates La Niña may develop during July-September 2024 and then persist through the Northern Hemisphere winter. The forecast team is also favoring the development of La Niña during July-September because the rate of cooling has slowed since last month. The team still favors La Niña to emerge sometime during the summer months, given the persistent below-average subsurface ocean temperatures and changes in the tropical atmospheric circulation. In summary, ENSO-neutral conditions are present. La Niña is favored to develop during July-September (65% chance) and persist into the Northern Hemisphere winter 2024-25 (85% chance during November-January; ”

Below is the middle paragraph from the discussion last month.

“The most recent IRI plume favors an imminent transition to ENSO-neutral, with La Niña developing during July-September 2024 and then persisting through the Northern Hemisphere winter. The forecast team continues to favor the dynamical model guidance, which suggests La Niña could form as early as June-August 2024 [Author’s Note: slipped a month which is not a big surprise], with higher confidence of La Niña during the following seasons. La Niña generally tends to follow strong El Niño events, which also provides added confidence in the model guidance favoring La Niña. In summary, a transition from El Niño to ENSO-neutral is likely in the next month. La Niña may develop in June-August (49% chance) or July-September (69% chance).”

We now provide additional details.

CPC Probability Distribution

Here are the new forecast probabilities. The probabilities are for three-month periods e.g. MAM stands for March/April/May.

Here is the current release of the probabilities:

This chart shows the forecasted progression of the evolution of ENSO from the current El Nino State to Neutral and by the summer to La Nina.  This kind of bar chart is not very good at showing uncertainty.

Here is the forecast from last month.

The analysis this month and last month are a bit different with again the transition to La Nina being slower than thought last month.

…There are Excessive Heat Warnings/Watches and Advisories over Southern
California, Southwest, Central Plains, and Southern High Plains on
Thursday…

A front extending from the Upper Great Lakes, Upper/Middle Mississippi
Valley, and then westward to the Central Rockies will move eastward to the
Northeast Coast, Mid-Atlantic, and westward to the Middle Mississippi
Valley and Central Plains by Saturday. The boundary will trigger showers
and severe thunderstorms over parts of the Middle Mississippi
Valley/Western Ohio Valley. Therefore, the SPC has issued an Enhanced Risk
(level 3/5) of severe thunderstorms over parts of the Middle Mississippi
Valley/Western Ohio Valley through Friday morning. The hazards associated
with these thunderstorms are frequent lightning, severe thunderstorm wind
gusts, hail, and a few tornadoes. In addition, there will be an added
threat of severe thunderstorms wind gusts of 65 knots or greater from the
Central Plains to Western Ohio Valley. Further, there will be an added
threat of large hail, two inches or greater, from the Central Plains to
the Western Ohio Valley.

On Friday, the boundary moves eastward to the Northeast, producing showers
and severe thunderstorms over parts of the northern Mid-Atlantic/New
England. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
thunderstorms over parts of the northern Mid-Atlantic/New England from
Friday through Saturday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts, and
a minimal threat of tornadoes/ hail.

In addition, along the western end of the front, showers and severe
thunderstorms will develop over parts of the Central High Plains.
Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
thunderstorms over parts of the Central High Plains from Friday through
Saturday morning. The hazards associated with these thunderstorms are
frequent lightning, severe thunderstorm wind gusts, hail, and a few

of the Middle Mississippi Valley to the Central/Southern Appalachians.

Meanwhile, on Thursday, a stationary front with waves will extend across
northern Florida and parts of the Gulf of Mexico, and the combination of
tropical moisture over southern Florida will produce showers and
thunderstorms with very heavy rain over parts of southern Florida.
Therefore, the WPC has issued a Moderate Risk (level 3/4) of excessive
rainfall through Friday morning. The associated heavy rain will create
numerous areas of flash flooding. Furthermore, many streams may flood,
potentially affecting larger rivers.

On Friday, the threat of excessive rainfall will decrease slightly over
the southern tip of Florida. Therefore, the WPC has issued a Slight Risk
(level 2/4) of excessive rainfall over southern Florida from Friday into
Saturday morning. The associated heavy rain will create mainly localized
areas of flash flooding, with urban areas, roads, small streams, and
low-lying areas the most vulnerable.

Elsewhere, on Friday, a front will develop over parts of the Pacific
Northwest and move inland to the Northern Plains, the Great Basin, and
Southern California. The system will produce showers and thunderstorms
over parts of the Northern High Plains and Northern Plains on Friday
evening into Saturday. Moreover, onshore flow behind the front will
produce rain over parts of the Pacific Northwest from Friday to Saturday.

Moreover, upper-level ridging will develop over parts of the Southwest
eastward to the Southern, leading to Excessive Heat Warnings/Watches and
Heat Advisories over Southern California, Southwest, Central Plains, and
Southern High Plains. Residents and individuals involved in outdoor
activities must stay informed and take immediate and necessary precautions.

A front extending from the Southeast across the Gulf Coast into the
Southern Plains will make the eastern portion quasi-stationary over the
Southeast. At the same time, the western half dissipates on Wednesday. The
half of the west of the boundary will aid in creating showers and severe
thunderstorms over parts of south-central Texas. Therefore, the SPC has
issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the
Southern Plains through Wednesday morning. The hazards associated with
these thunderstorms are frequent lightning, severe thunderstorm wind
gusts, hail, and a minimal threat of tornadoes.

Furthermore, showers and thunderstorms will develop along the eastern
portion of the front. The combination of tropical moisture and upper-level
impulses will aid in producing showers and thunderstorms with heavy rain
over parts of southern Florida. Therefore, the WPC has issued a Slight

In addition, the tropical moisture will continue to produce showers and
thunderstorms with heavy rain over parts of southern Florida. Therefore,
the WPC has issued a Slight Risk (level 2/4) of excessive rainfall from
Wednesday into Thursday morning. The associated heavy rain will create
mainly localized areas of flash flooding, with urban areas, roads, small
streams, and low-lying areas the most vulnerable.

Meanwhile, an upper-level low over the Northeast will help develop rain
with daytime-embedded thunderstorms over the area on Tuesday and Wednesday.

Elsewhere, another front over the Upper Mississippi Valley extending
southwestward to the Central Rockies/Great Basin will move eastward to the
Great Lakes and dissipate by Wednesday evening. On Tuesday, the front will
produce showers and thunderstorms over parts of the Upper Mississippi
Valley/Upper Great Lakes into the Central Plains and Central Rockies.

On Wednesday, moisture pooling along the boundary will create showers and
severe thunderstorms over parts of the Upper Mississippi Valley.
Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
