Geopotential height of the SH polar vortex has Positive correlation with the AAO

An incredible correlation between vertical geopotential height and the phase of the AAO.

Amazing l have never noted that before. A light bulb moment.

When geopotential height between surface to 100 hPa is positive . The AAO index is negative.
When geopotential height between surface and 100 hPa is negative. The AAO index is positive.

Some convincing proof that the condition of the polar vortex affects our weather.
I will put this geopotential height anomaly in the polar vortex on my weekly observation  round.

Climate shifts…natural variation

I have started this blog post because today l have found out all major search engines are re routing the search string ‘climate shift’.

If you enter this term into any search engine, it will respond with pages and pages of ‘climate change’

We are being prevented from viewing alternative theories to man made climate change theories or facts, folks.

I will make an attempt to collect some links to climate regime shift sites that focus on natural variability.

I have tried alternatives to google and they ALL redirect the term ‘climate shift’

…You can get around this by..

Using google scholar…

which will accept the string ‘climate shift’ and lead you to alternative research on the reasons for global temperature trends other than AGW


on on the main google search engine page use talking marks on the search string which over rides the ban on the term… climate shift

Troposphere height

Theory. Height of the troposphere


‘The height of the tropopause depends on the location, notably the latitude, as shown in the figure on the right (which shows annual mean conditions). It also depends on the season (1, 2). Thus, it is about 16 km high over Australia at year-end, and between 12 – 16 km at midyear, being lower at the higher latitudes. At latitudes above 60� , the tropopause is less than 9 -10 km above sea level; the lowest is less than 8 km high, above Antarctica and above Siberia and northern Canada in winter. The highest average tropopause is over the oceanic warm pool of the western equatorial Pacific, about 17.5 km high, and over Southeast Asia, during the summer monsoon, the tropopause occasionally peaks above 18 km. In other words, cold conditions lead to a lower tropopause, obviously because of less convection.

Deep convection (thunderstorms) in the Intertropical Convergence Zone, or over mid-latitude continents in summer, continuously push the tropopause upwards and as such deepen the troposphere. This is because thunderstorms mix the tropospheric air at a moist adiabatic lapse rate. In the upper troposphere, this lapse rate is essentially the same as the dry adiabatic rate of 10K/km. So a deepening by 1 km reduces the tropopause temperature by 10K. Therefore, in areas where (or at times when) the tropopause is exceptionally high, the tropopause temperature is also very low, sometimes below -80� C. Such low temperatures are not found anywhere else in the Earth’s atmosphere, at any level, except in the winter stratosphere over Antarctica.

On the other hand, colder regions have a lower tropopause, obviously because convective overturning is limited there, due to the negative radiation balance at the surface. In fact, convection is very rare in polar regions; most of the tropospheric mixing at middle and high latitudes is forced by frontal systems in which uplift is forced rather than spontaneous (convective). This explains the paradox that tropopause temperatures are lowest where the surface temperatures are highest.

The tropopause height does not gradually drop from low to high latitudes. Rather, it drops rapidly in the area of the subtropical and polar front jets (STJ and PFJ respectively in the Figure on the left), as shown in the Palmen-Newton model of the general circulation (Fig 12.16 or Fig on left). Especially when the jet is strong and the associated front at low levels intense, then the tropopause height drops suddenly across the jet stream. Sometimes the tropopause actually folds down to 500 hPa (5.5 km) and even lower, just behind a well-defined cold front. The subsided stratospheric air within such a tropopause fold (or in the less pronounced tropopause dip) is much warmer than the tropospheric air it replaces, at the same level, and this warm advection aloft (around 300 hPa) largely explains the movement of the frontal low (at the surface) into the cold airmass, a process called occlusion (Section 13.3) (4).

Is the NASA modelling of the Maunder minimum ozone levels correct?
In this article l have described two cases that made me doubt..?
Read on…


AROSA ozone timeseries

Total ozone series in Arosa, Switzerland

    Background of the NASA modelling

NASA article


“During the Maunder Minimum, the Sun emitted less strong ultraviolet light, and so less ozone formed.
The decrease in ozone affected planetary waves, the giant wiggles in the jet stream that we are used to seeing on television weather reports.


global ozone map

Will have to check this OZONE ‘thingy’ out in more detail one day soon

So.. Whats UP??

The time series of TOTAL OZONE at AROSA Switzerland seems to contradict NASA models findings?

At AROSA ..OZONE concentration went DOWN during global warming and has increased at AROSA since the global warming stall or hiatus..!!
OZONE measurements in AROSA..SWITZERLAND have increased since 1992?

The NASA model indicates a solar downturn should produce less ozone not more as is the case at AROSA since 1992

Maybe there is difference between the trends in surface ozone and stratospheric ozone?


    Now further to this apparent contradiction

A recent stratospheric warming event ( SSW ) in the southern hemisphere in the first week of August 2013 is currently registering on the OZONE concentration map as a strong positive anomaly on August 14 th 2013

captured in the snap l took below
ozone created in stratospheric warming event

In other words the stratospheric warming event created MORE ozone

So the warm air created MORE …. not less ozone..

Investigation required!!

I undertook a case study on the SSW event here
