New Type of SLC Detection Model - 4

Fig. 1 Down to Three

In the final analysis the GeoZones "aa" - "br" were not the best way to set up the grid.

Too many squares (New Type of SLC Detection Model - 4).

It is down to 3 zones now.

They are: 1) "np" which is the North Polar Area, ("49th parallel" or Lat. 49 N. to the North Pole); 2) "sp" the South Polar Area (-60 deg. S. to the South Pole), and, 3) "eq" the area in between, with the Equator at about mid-point.

Fig. 2 SLC (SLR / SLF)

It also matches the three-zone concept of the scientists who fashioned them according to primary ice mass locations.

The graphs displayed below (Fig. 3 - Fig. 6) show one example of how they finger trends easier than the 38 smaller zones did.

The same number of stations are used in this concept as I was working with after culling and discontinuing irrelevant stations.

There are 151 stations in the "np" zone, 1 in the "sp" zone, and 337 in the "eq" zone (489 total).

I don't know if more tidal gauges can be used in the "sp" zone (look on Fig. 1 to find it ... int is basically ice-surrounded Antarctica).

The one gauge in that vast area is "ARGENTINE ISLANDS" at Lat. -65.2462311, Lon. -64.2574158.

Fig. 3 Lows and Highs

I discovered that, in the "np" zone the sea level fall (SLF) is taking place at certain latitudes

Notice on Fig. 3, that the low sea levels are between about 55 deg. N and 60. deg. N. latitude.

That is the area of Glacier Bay and the other Southeastern Alaska Range glaciers where there is a lot of land ice mass.

The bottom third of Fig. 2 shows that area to be the prime area for SLF as the glaciers and mountain ice flows into the Gulf of Mexico.

Fig. 4 Mean Lows and Highs

Thus we have a clear fingerprint, a clear indication that they are and have been very busy melting and calving for some time (Proof of Concept).

It is much easier to detect with the zones down to three, and those zones in sync with the only three SLF zones on the globe.

Fig. 5 Mean Average

Only the Arctic, Antarctica, and the Alaska area are expected to be centers of SLF.

All the others are sea level rise (SLR) areas in the normal sense of the dynamics of SLC.

Anyway,, Fig. 5  also has the same finger print, those low sea level points between about Lat. 55 N. and Lat. 60 N.

All of these graphs use the values of all of the 151 tidal stations in the "np" zone, and aggregate their values, so they all tell the same story.

Fig. 6 All 151 "np" stations

The busy Fig. 6 is all of the aggregated values placed on one graph.

It tells the same story about the SLF dynamics being in the same location, which is the Southeastern Alaska region, that contains, among other things, Glacier Bay National Park.

I am now going to tie in the future calculation logic, which was working with the 38 zones, but was not working well enough.

There was just too much mixing of different areas (e.g. Southern California was in the same zone as the East Coast).

Now, all the stations used for a particular purpose will be in the same zone and the zones do not have conflicting member stations now.

Longitude values can be used to group stations in the way they should be with latitude merely separating the major ice zones (Greenland, Antarctica) in polar regions.

Every zone now has all longitudes in it, the zone separation lines now being latitude values.

Zones have their distinct and unique latitudes, but all zones have all of the longitude values (San Diego can be excluded from East Coast computations via longitude now ... it was in zone "al" before as was the East Coast).

I will, hopefully, be able to write some about the future projection logic in a day or two.

If I can tie in the modules that do extensive calculations, rather that the SLC-Lite version, I will.

Thanks for stopping by.
