I don't have an explanation except to speculate that the multidecadal enhancement of the zonal sea surface temperature gradient (like what was described in this post) is helping to keep the tropical atmosphere more La Nina-like even when the typical ENSO sea surface temperature indexes are deviating from typical La Nina values. In the SPEAR simulations, I examined the relationship between the ensemble mean Southwest U.S. precipitation anomalies and the La Nina SST anomalies. This precipitation forecast has a lot do with La Nia, which has already started to settle in. Water in Rillito River east of Swan Road and clouds from a clearing winter storm around the Santa Catalina Mountains north of Tucson on Dec. 12, 2022.

According to the Old Farmer's Almanac, winter will arrive early this year for the province, with frigid temperatures dropping down from the Yukon and northern Alberta by mid-to-late November. This is calculated as the deviation of the 30 ensemble members from the average for each individual La Nia event, and so I wind up with a total of 630 deviations from the ensemble average that capture precipitation variations resulting from the uncertainty in the initial conditions, i.e., chaotic weather variability. Here is what the Met Office is predicting for the coming weeks. So what exactly does this mean for the winter weather patterns and snowfall potential? Most of Europe is forecast to have less snow depth by mid-winter. As that post notes, it's critical to understand the source of the mismatch models and observations (natural variability or model error or both?

The emerging La Nia weather pattern plays a part in this year's winter outlook. The La Nina is set to break down going into Spring, with a warm phase (El Nino) chances increasing for late 2023. We will look at two highly regarded seasonal weather forecasting systems. The pattern seems to be under the influence of a high-pressure system, as the forecast does not permit a lot of large-scale snowfall scenarios and snow accumulation. Most Mediterranean-like climates ( like South-West Australia, Cape Canaveral , Chili mid-west, East Mediterranean countries and South California ) were pre-forecast to have drier than normal Early winter but showed wetter Mid-winters and hopefully the rest of the winter will be wetter . ET. So what's in store? Probably the coupling of weak Polar vortex with the recurrent PV stratospheric warming has something to do with the Southward (equator-wise) migration of Atmospheric wet Rivers in mid to late winter , this last point is well-documented in many physical science papers that weak polar vortex post SSW events tend to measure more equator-wise migration of the Jetstream causing these atmospheric rivers to bring wetter than normal events to California and many mediterranean-like climates in the northern hemisphere late winter. Drought improvement in the Southwest continues As of July 26, 2022, over 50% of the contiguous U.S. was in drought, with almost 20% in the two worst categories, extreme and exceptional drought (D3-4), a slight increase since late June. This fits the long term trend across our area during a La Nia phase of slightly above normal temperatures during the . This is typically on the western and southern border of low-pressure systems, where the northerly and northwesterly flow pulls down cold air from the north. I am wondering if there is a possibility that the triple-dip La Nina event from 2020 could create some kinds of conditions that make atmospheric rivers more active, resulting in the occurrence of torrential rains over the western United States. Despite the headlines, the winter weather predictions from both publications have a lot of similarities this year. The December snow depth forecast shows widespread negative anomalies. This will most likely result in wintry showers, these turning more organised at times in the north and east. While AccuWeather forecasts that snowfall will be suppressed, the company does not necessarily expect overall precipitation to be below normal as well, with milder temperatures leading to several all-rain events this winter. It looks like an interesting study, and it relates to last month's blog post on the discrepancy between observed and modeled Pacific sea surface temperature trends.

The February snowfall forecast shows snowfall potential remaining over the northern parts of the United States. I saw this same behavior in my analysis of the SPEAR climate model simulations, which increases confidence that this more robust dry signal in February-March is a real phenomenon. The cold phase is called La Nina, and the warm phase is called El Nino. Year-Long Guide to Great Living The 2023 Farmers' Almanac offers 16 months of weather prediction starting with September 2022 going through December 2023. If the response is linear and the normal response is dry, one would expect the wet La Nias to be more likely to be weak ones and the very dry La Nias to be more likely to be strong ones. The more forecast data you can look at, the better idea you can get about the expected weather patterns. Resources such as drought.gov and climate.gov provide comprehensive tools to better understand and plan for climate-driven hazards. The standard deviation of this set of values is 0.725 mm/day. In the West, the drought persists. Much of this snowfall does not settle, and the figures for snow on the ground (snow lying) are much lower. The colder air is more easily accessible to the northern United States, which increases the snowfall potential if enough moisture is available. The figure below shows that most (13 of 21) of the La Nias from 1951-2020 had below-average December-January precipitation in this region (1), although wet early winters during La Nia clearly are not that unusual. It was developed by the United Kingdom Met Office, which is where the initials UKMO come from. Typically, the first influence of these ocean anomalies can be seen in the jet stream patterns changing. A blog about monitoring and forecasting El Nio, La Nia, and their impacts. The remainder of the U.S. falls into the category of equal chances for below-, near-, or above-average seasonal total precipitation. AccuWeather's 2022-2023 Canada winter forecast La Nia is expected to affect winter weather in Canada for the third straight year. It's important to keep in mind that not every location in the Southwest has been wetter than normal lately.
