Changes in obliquity modulate seasonal contrasts as well as
annual mean insolation changes with opposite effects at low vs. high latitudes (and therefore no effect on global average insolation)-LCB- 6.4 -RCB-.
Not exact matches
Seasonal changes in
insolation are much larger than
annual mean changes and can reach 60 W m — 2 (Box TS.6, Figure 1).
Dry climates have a higher
mean annual temperature than wet cllimates when
insolation is the same at top of atmosphere.
All this
means is that Phoenix gets about 30 percent more

insolation» — than Atlantic City, which receives 4.7 kWh / square meter in an average year.
Excuse me for pointing you to a physical oceanography textbook used by Texas A&M University and in particular to Figure 5.8 Global map of
annual -
mean insolation into the sea in W / m2 calculated from the ECMWF 40 - year reanalysis.
