La Nina, which worsens hurricanes and drought, is gone

WASHINGTON (AP) — After three nasty years, the La Nina weather phenomenon that increases Atlantic hurricane activity and worsens western drought is gone, the National Oceanic and Atmospheric Administration said Thursday. That’s usually good news for the United States and other parts of the world, including drought-stricken northeast Africa, scientists said.

The globe is now in what’s considered a “neutral” condition and probably trending to an El Nino in late summer or fall, said climate scientist Michelle L’Heureux, head of NOAA’s El Nino/La Nina forecast office. “It’s over,” said research scientist Azhar Ehsan, who heads Columbia University’s El Nino/La Nina forecasting. “Mother Nature thought to get rid of this one because it’s enough.”

La Nina is a natural and temporary cooling of parts of the Pacific Ocean that changes weather worldwide. In the United States, because La Nina is connected to more Atlantic storms and deeper droughts and wildfires in the West, La Ninas often are more damaging and expensive than their more famous flip side, El Nino, experts said and studies show.

Generally, American agriculture is more damaged by La Nina than El Nino. If the globe jumps into El Nino it means more rain for the Midwestern corn belt and grains in general and could be beneficial, said Michael Ferrari, chief scientific officer of Climate Alpha, a firm that advises investors on financial decisions based on climate.

3. Where more hurricanes had formed this past season

was in the Pacific! However the Atlantic ones were stronger and costlier thanks to climate change.

4. Not true at all about the Atlantic storms except cost
Thu Mar 9, 2023, 12:25 PM
Mar 2023

Overall, the 2022 Atlantic hurricane season featured near normal
activity in terms of the number of named storms and hurricanes, but
was slightly below average in terms of the number of major
hurricanes.

...In terms of Accumulated Cyclone Energy
(ACE), which measures the strength and duration of tropical storms
and hurricanes, activity in the basin in 2022 was slightly
below average. The ACE for 2022 is 80 percent of the long-term
(1991-2020) mean.

The higher cost is due to where the storms hit and the extreme appreciation of property values in those areas over the last few years.

6. It's a hobby and I have been posting on a weather forum since before I joined DU

meaning almost 17 years.

The 2022 Atlantic hurricane season had 14 named storms and the Pacific hurricane season had 19 named storms (including 2 Atlantic systems that crossed over into the Pacific).



So what I wrote was correct. I tracked the damn things (I run GRLevel 3 and GR2Anayst).

Damaging 2022 Atlantic hurricane season draws to a close
NOAA science and services yield improved forecasts

November 29, 2022

(snip)

In total, this hurricane season produced 14 named storms (winds of 39 mph or greater), of which eight became hurricanes (winds of 74 mph or greater) and two intensified to major hurricanes with winds reaching 111 mph or greater. An average hurricane season has 14 named storms, seven hurricanes and three major hurricanes.

Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM PST Thu Dec 1 2022

For the eastern North Pacific, east of 140 degrees west longitude:

No tropical cyclones formed in the eastern Pacific basin in the
month of November. Based on a 30-year climatology (1991-2020), one
named storm typically forms in November every second or third
year. This is the first November since 2017 in which a named
storm did not form during the final month of the hurricane season.

Overall, the 2022 eastern Pacific hurricane season featured an
above average number of named storms and hurricanes, and an average
number of major hurricanes. Seventeen named storms formed in the
basin in 2022 (Bonnie and Julia are not included since they formed
in the Atlantic basin).
Ten hurricanes occurred in the basin with
four of those becoming major hurricanes (category 3 or greater on
the Saffir-Simpson Hurricane Wind Scale). This compares to the
long-term (1991-2020) averages of fifteen named storms, eight
hurricanes, and four major hurricanes. In terms of Accumulated
Cyclone Energy (ACE), which measures the strength and duration of
tropical storms and hurricanes, the activity in the Eastern Pacific
was near the long-term (1991-2020) average.

Reports on individual cyclones, when completed, are available at
the National Hurricane Center website at:
www.nhc.noaa.gov/data/tcr/index.php?season=2022&basin=epac

9. What did I say in my OP? Not true for "Atlantic storms".
Thu Mar 9, 2023, 01:05 PM
Mar 2023

There is nothing in your link about Atlantic storms being stronger (or anything about climate change). One of them (Ian) came ashore as the 5th strongest storm ever, but, overall, it was an average year based on the number of storms and slightly weaker based on the ACE.

And you somehow convoluted it into something else.

The first link has this in the summary -

Hurricane Ian tied for the fifth-strongest hurricane ever to make landfall in the U.S.


Ian had 150+ mph sustained winds at landfall in FL, almost like what happened with Hurricane Michael when it hit Mexico Beach, FL (we have DUers who in live that area of Ft. Myers and Cape Coral where it hit). None of the named E./Central Pacific hurricanes of 2022 reached that sustained level of winds whether land-falling or over open waters.

2. Thank god. So much of the West is parched. It's very dangerous. I'm not wild about

El Nino because it brings so much more rain and snow to the Northwest of he country but, I'll take it any day over this long, killing drought.

wildfires in west are terrible. I have not lost my home but lived with smoke and concern for several summers. Driven to see damage after event and it is horrible. And learning of others losses.
