Sentences with phrase «high obliquity»

I would hazard a guess that during periods of high obliquity that ozone holes have naturally developed.

Note Pluto seems to have a very high obliquity; the atmosphere is on the edge of an atmospheric phase transition; and there is a possibility of volcanism (Pluto has a large, close moon — Triton's short term atmospheric variability is almost certainly due to variable volcanism).

«At high obliquity, temperatures over mid-to-high latitude continents would reach near boiling 80 to 100 Celsius around the summer solstice under a 1 - bar nitrogen - dominated atmosphere.

We used asteroseismology to measure a large obliquity for Kepler - 56, a red giant... ▽ More Stars hosting hot Jupiters are often observed to have high obliquities, whereas stars with multiple co-planar planets have been seen to have low obliquities.

Abstract: Stars hosting hot Jupiters are often observed to have high obliquities, whereas stars with multiple co-planar planets have been seen to have low obliquities.

Not exact matches

Huybers (Quaternary Science Reviews, 26, 37) has proposed a simple model in which deglaciation is triggered when the obliquity cycle is high, and when ice mass is sufficiently high.

Precession dominates * midsummer * high - latitude insolation (the usual Milankovitch metric), but obliquity has a stronger influence on Huybers» notion of «summer heat» (which takes into account the astronomical influence on length - of - season.

Smaller obliquity transfers annual average insolation from higher latitudes (would make polar regions darker) to lower latitudes and reduces the seasonal ranges (would make winters less dark for less long).

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-.

MILANKOVITCH CYCLES overall favor N.H. cooling and an increase in snow cover over N.H high latitudes during the N.H summers due to the fact that perihelion occurs during the N.H. winter (highly favorable for increase summer snow cover), obliquity is 23.44 degrees which is at least neutral for an increase summer N.H. snow cover, while eccentricity of the earth's orbit is currently at 0.0167 which is still circular enough to favor reduced summertime solar insolation in the N.H. and thus promote more snow cover.

Huybers (Quaternary Science Reviews, 26, 37) has proposed a simple model in which deglaciation is triggered when the obliquity cycle is high, and when ice mass is sufficiently high.
