TOPOGRAPHY

BLOCKAGE

Major: 235-255 deg beyond about 12km, 55-65 deg beyond 48km
Minor Sectors: Some partial blockage 50-100 deg beyond about 50km, and 265-270 beyond 45km
Minor Isolated (tower/trees/etc):

It is hard to quantify but long term accumulations suggest the entire sector from 20-265 is partially blocked in winter.

A 24 hour accumulation illustrating typical pattern of blockage.


SEA/LAKE CLUTTER

Serious to NW beyond about 50km
Distance to horizon from an on-line calculator = 97 km (http://www.ringbell.co.uk/info/hdist.htm, apparently geometric with no refraction, so add approx 10% at radar wavelength.)


WIND TURBINES

Yes about 4 farms along river to north.


ROADS/HYDRO/etc

In long term statistics one can see shipping lanes in rain accumulations, up and down lanes in St Lawrence and a ferry across the river.
