Another helpful weather link in terms of education...

Checkout this site I discovered yesterday - WeatherSpark:

http://weatherspark.com/#!graphs;ws=305 ... dewPoint:0

You can choose just about any observation site in the world and see a plot of the temperature going back many decades. There's a 5-day forecast temperature plot based on model guidance. Models can be plotted on the map, as they are on the link above.

What's really neat is you can go back in time to look at the temps during big freeze (or heat) events. For those of you not around in 1983, check out the big Christmas freeze where IAH was below freezing for 5 straight days.

http://weatherspark.com/#!graphs;ws=305 ... dewPoint:0

Use your mouse wheel to adjust the span of the graphic. This allows you to zoom in to see a single day or zoom out to view the trace for the whole year.

That is a cool site. I bookmarked it. Thanks

Also hopefully over the break I hope to update the first post a little. I will fix any broken links etc....

Linear Correlations in Atmospheric Seasonal/Monthly Averages
http://www.esrl.noaa.gov/psd/data/correlation/

I ran Linear Correlations in Atmospheric Seasonal/Monthly Averages and found the August to October sea level pressure in the Atlantic is correlated with ENSO. Warmer the ENSO, the higher the pressure.

There is a negative correlation with Antarctic Oscillation (AAO) and summer temperature in the Western US. That means the more positive AAO is, the cooler it is for Western US, especially Rocky Mountain region.

There is a negative correlation with Quasi-Biennial Oscillation (QBO) and winter rainfall in South and Southeast Texas. The more easterly or negative QBO is, the wetter winter is.

You can map out weather data that goes way back depending on weather event, like drought or El Nino.

Climate Time Series
http://www.esrl.noaa.gov/psd/gcos_wgsp/Timeseries/

You can find Arctic Oscillation (AO) data that is re-analyzed from 1891. The winter of 1894-1895 and 1898-1899 were negative AO.

I will come to help with information about a weather page, that I hope to use it with pleasure.

Threaded Extremes
http://threadex.rcc-acis.org/

From the site:
ThreadEx is a project designed to address the fragmentation of station information over time due to station relocations for the express purpose of calculating daily extremes of temperature and precipitation. There are often changes in the siting of instrumentation for any given National Weather Service/Weather Bureau location over the observational history in a given city/region. As a result, obtaining a long time series (i.e., one hundred years or more) for computation of extremes is difficult, unless records from the various locations are "threaded" or put together. This has been done, but different approaches and combinations of stations have resulted in confusion among data users and the general public about what constitutes an official daily extreme record.

The Coriolis effect
The air flows in these three circulation belts or cells do not move in a straight north to south or south to north route. Instead, the air flows seem to move east to west or west to east. This effect was first identified by the French mathematician Gaspard-Gustave de Coriolis (1792–1843) in 1835. Coriolis observed that, because of the spinning of the planet, any moving object above Earth's surface tends to drift sideways from its course of motion. In the Northern Hemisphere, this movement is to the right of the course of motion. In the Southern Hemisphere, it is to the left. As a result, surface winds in Hadley cells—both in the equatorial and polar regions—blow from the northeast to the southwest in the Northern Hemisphere and from the southeast to the northwest in the Southern Hemisphere. Surface winds in Ferrell cells tend to blow in the opposite direction: from the southwest to the northeast in the Northern Hemisphere and from the northwest to the southeast in the Southern Hemisphere.
