Not really. Due to the use of the radial pattern, the blend area gets
thinner towards the poles, pinching to a point at the poles. In real
life, it is constant. (Actually, getting slightly thicker, due to the
oblate shape of the planet.)
The gradient or slope patterns are more suited to this application.
Rotating the pattern is as simple as rotating the gradient or slope
vectors.
