You can nicely see the developing cold waveforms, as the pressure patterns are creating strong easterly surface trade winds. The reason for the warming can actually be seen already, as it is lurking below the ocean surface in the equatorial Pacific. That shift is why some of you literally experienced a season shift over night, but there is more. The complex relationships among temperature, density, pressure, and wind are further discussed at this link, but the recent weather whiplash event is rooted in troughs, ridges, and temperature gradients. In fact, a handful of sunshiny days seem to be in our future, as of publication. Even though it might've felt cold, this summer actually has seen warmer than average temperatures. This is the likely result of the current warm Kelvin wave at depth, making its appearance on the ocean surface. ECMWF produces these extended seasonal forecasts every few months. Insight and analysis of top stories from our award winning magazine "Bloomberg Businessweek".

Even here in the South, temperatures in the seventies gave way to snow in parts of Alabama and Georgia. The warming and resulting weather events that we see today are a reaction to emissions that entered the atmosphere decades ago. As humankind's emissions of heat-trapping greenhouse gases have warmed the planet, the heating has not been uniform. This can be an indication that we are heading towards a new grand minimum, but it can also be a Dalton minimum type, like seen on the image above in the early 1800s. Below we can see the solar cycles through the last decades, and the current solar minimum. According to the National Weather Service Jet Stream website, The areas of lower heights (colder, more dense air) are called troughs.regions of higher heights (warmer, less dense air) are called ridges (graphic below)., The relationship among pressure, density, and atmospheric waves.

This is where ENSO generally perhaps loses its direct influence over Europe, as regional systems in the Atlantic are a major interference to any direct influence. But during a La Nina, the pressure over the equatorial Pacific is high, creating stable conditions and less precipitation. There were some bizarre temperature readings along the way. Contrails are simply exhaust consisting of water vapor spewing from a planes jet engine high in the atmosphere. Surface temperatures (GFS 1-day average) on Monday, January 3rd, 2022, Before discussing the whiplash, a term that I have seen frequently but may have been first used by Paul Beckwith, I start with an explanation of an inflatable bounce house. As meteorologists, we spend a great deal of time looking at upper air weather maps and model output trying to diagnose the amplitude of these waves, the location of the jet stream, and how they are moving. Categories Long range / seasonal forecast. We can see the average pressure anomalies below 0-30 days after an SSW event. And it was only the 18 th coolest March; only one of the coolest 10, March 2002, has occurred since 1976. It heats up, reduces cloud cover, and allows more sun to bake the ground, he explains. Siberia is battling wildfires again. Depending on wind speeds, the amount of humidity in the air, and other factors, some contrails will either stay thin and dissipate into the air or linger and spread over minutes, or even hours. It is influenced by the pressure patterns of the El Nino from below and interacts with the high atmospheric patterns of the QBO. Vehicles drive through a waterlogged road after a heavy monsoon rainfall in Mumbai. Looking over the years, we can see that from the top 5 most active tornado years, 4 were actually La Nina seasons.
