Tilt and Seasonal Insolation
qThe hemispheric and seasonal patterns of insolation changes
for tilt and
precession are fundamentally different.
qInsolation changes at high latitudes caused by change in the tilt are
in phase between the hemisphere from a seasonal perspective.
qFor the
case of increased tilt, summer insolation maxima in the northern hemisphere occur at the
same time
in the 41,000-year cycle as summer insolation maxima in the southern hemisphere.
