dryness
S
by Drew Lerner
erious drought was enhanced by blistering heat at
times in June from the western United States into
western Canada. Reports of dwindling water supply
and fears of extreme water shortages made headlines
along with never-before-seen temperatures of up
to 118 degrees Fahrenheit in the US Pacific Northwest.
The concerns are real, and now that evidence is beginning
to rise over the potential return of La Niña late
this year, those concerns are likely to be perpetuated
into 2022.
World Weather, Inc. is convinced that we are moving
into a period of multiple dry years in North America
that will present hardship that some farmers and consumers
have not had to deal with in decades, and for
some folks their entire lifetime. There is increasing evidence
that the same mechanisms responsible for multiple
dry years in the 1980s, 1950s, 1930s, the early
1900s and a couple of times in the 1800s are coming
together once again.
The current drought encompassing much of western
North America is the perfect seedling to troubles that will
continue in 2022. Some computer forecast models are now
suggesting La Niña will return late this year. If that happens,
World Weather, Inc. believes it may last for a much
longer period than that which occurred last year. The evolution
of La Niña will be occurring simultaneously with
the negative phase of Pacific Decadal Oscillation (PDO),
and both will be occurring in a 22-year solar cycle that
has promoted more significant droughts in North America
than at other times in the solar cycle.

A PERFECT RECIPE FOR LENGTHY
Conditions are favorable for multiple dry years in North America
PDO is an ocean temperature phenomenon that tends
to have great influence on North American weather, especially
in the summer. The PDO has a negative phase
and a positive phase. The negative phase includes cooler-than-usual
ocean temperatures off the Pacific US
coast with warm water relative to normal over the central
North Pacific. The negative phase of PDO tends to
produce a deep trough of low pressure over the western
United States during the summer, which forces a summertime
ridge of high pressure to the east, resulting in
some excessive heat and dryness in parts of the Midwest
instead of favoring the Great Plains in other years.
La Niña creates multiple problems. First, the winter
tends to be drier than usual across the southern United
States. That would not bode well for California, the
southern Rocky Mountain region and northern Mexico,
which are hoping for a breakdown in drought conditions
during the coming summer and winter. Summer
rainfall in these areas may be close to normal but if
La Niña evolves, winter precipitation could be significantly
lighter than usual - like last winter. La Niña
also tends to produce below-average precipitation and
warmer-than-usual temperatures in the US Plains and
western Corn and Soybean Belt during the winter and
spring. If this summer ends drier than usual in the western
Corn Belt and Plains and is followed by La Niña
during the winter and spring, there may be a greater
moisture deficit to deal with at the beginning of the
2022 growing season.
La Niña summers tend to have less rainfall and warmJuly
