The Arctic Oscillation and Arctic Weather Patterns

This pattern tends to bring warm air from lower latitudes into the Arctic. —Credit: National Snow and Ice Data Center courtesy NOAA/ESRL PSD The unique geography of the Arctic leads to unique weather patterns that reappear in the region year after year. Some weather patterns, such as cyclones or anticyclones, occur in the Arctic as well as other regions. Other weather patterns, like the Arctic Oscillation, are specific to the Arctic. Cyclones and Anticyclones Cyclones, or low-pressure systems, are circular weather patterns that rotate in a counter clockwise direction.

Ryan Maue PhD Meteorology

Ryan N. Maue Dr. Judith Curry is quoted in a classic Seth Borenstein AP screed connecting disparate extreme weather events into a tidy AGW-narrative: “Sometimes it seems as if we have weather amnesia.” …Judith Curry of Georgia Tech disagreed, saying that while humans are changing the climate, these extremes have happened before, pointing to the 1950s… she is correct but just who/what is she disagreeing with?

The AP article sets up the typical “arguing amongst experts” debate where the non-expert journalist assembles the narrative. The AP article begins: “Nature is pummelling the United States this year with extremes. Of course we know that natural disasters occur globally, and are often modulated by the El Niño Southern Oscillation (e.g. Dr. I’m sure Masters is tired of the website hits and advertising revenue, but this statement is not scientific but anecdotal. The AP article continues: “What’s happening, say experts, is mostly random chance or bad luck.

Who says what? Dr. Dr. Arctic Sea Ice News and Analysis. On September 11, Arctic sea ice reached its likely minimum extent for 2015.

Arctic Sea Ice News and Analysis

The minimum ice extent was the fourth lowest in the satellite record, and reinforces the long-term downward trend in Arctic ice extent. Sea ice extent will now begin its seasonal increase through autumn and winter. In the Antarctic, sea ice extent is average, a substantial contrast with recent years when Antarctic winter extents reached record high levels. Please note that this is a preliminary announcement. Changing winds or late-season melt could still reduce the Arctic ice extent, as happened in 2005 and 2010.

Explanations

On one side of the isobar pressure is smaller than the isobar value, on the other side greater. A common metaphor is a topographic map with it's lines denoting height: mountains are equal to areas of high pressure, dales equal to lows. Similarly, we can talk about ridges and troughs (or valleys). Wind follows roughly the direction of the isobars so that if you walk along an isobar and the wind is blowing onto the back of your neck, the lower pressure is at your left hand side (in the Northern Hemisphere .. reverse the rule for the Southern Hemisphere) *. Furthermore, there are several local effects (e.g. the sea breeze) which affect wind and make this general rule not valid in such cases. The closer the isobars are to each other, the higher the wind speed. Between tropical and arctic areas, at so called mid-latitudes, the isobars tend to form closed circles round the lowest pressure.

This map shows the likelihood that total 3-month precipitation will be unusually high or low. What do I do next? If you see a colour over your region, possible responses include: Contact your local/regional meterological department and monitor their forecasts during the next 3 months.Consider who may be most affected by heavy or low rainfall.Review your contingency plans and update as necessary.

How to Forecast Weather. Ever wondered how to forecast the weather without actually using instruments? Check the Clouds: Clouds can tell us a lot about the weather. For example, they can tell us if it’s going to be warmer on a particular night by simply being there. That’s because they prevent heat radiation from escaping. They can also tell you whether there will be rain and whether there will be bad weather in general (when you see clouds moving in opposite directions of each other). Check the Humidity: If you’re one of those people whose hair gets all curly when it gets really humid out, you know exactly what this is about. Check the Animals: Birds only fly in the sky when they expect fair weather ahead.

Look at the Rainbow (but only in the west) and look for a Red Sky: If you see one in the west, it means a major storm front is coming. Check the Air:
