Sentences with phrase «hemisphere summer when»

The direct radiative forcing (DRF) is strongest in the Northern Hemisphere summer when the insolation is the highest although different seasonal cycles of the sulphate burden from the chemical transport models result in maximum global mean radiative forcings ranging from May to August (e.g., Haywood and Ramaswamy, 1998), the ratio of the June - July - August / December - January - February radiative forcing being estimated to lie in the range less than 2 (e.g., van Dorland et al., 1997) to > 5 (e.g., Penner et al., 1998b; Grant et al., 1999) with a mean of approximately 3.3.

The earth absorbs more sunlight during the southern hemisphere summer when the darker (all that ocean) southern hemisphere is pointed more towards the sun This seasonal cycle may be large enough to overwhwlm the warming from CO2 etc for a year or so, thus on a seasonal scale the rise may not be monotonic.

Alignment of perihelion near winter solstice would reduce the annual average insolation (because that hemisphere'til ts away» from the sun during the time of year when global TOA insolation is largest) while reducing the seasonal range (tendency for cooler summers, warmer winters - but also, longer spring - summer and shorter fall - winter because the Earth's angular speed around the Sun is faster when Earth is closer to the Sun.

The National Climatic Data Center has released its review of worldwide sea surface temperatures for August and for the stretch from June through August and finds that both the month and the «summer» (as looked at from the Northern Hemisphere) were the warmest at least since 1880, when such records were first systematically compiled.

Glacial periods give way to interglacials on some occasions when the Northern Hemisphere's summer solar insolation (the amount of solar radiation received by Earth's surface) increases alongside corresponding decreases in ice volume and increases in temperature and atmospheric carbon dioxide (CO2).
