WebJan 24, 2024 · The orbital-only ensemble has trends similar to the full-forcing simulations in all variables over the Asian region: significant positive trends in 200mb winds at northern latitudes and negative trends at southern latitudes of central Asia, warming over subtropical Asia, and increased 200mb geopotential heights as well as T200 over the Indian … WebFeb 2, 2024 · Orbital forcing is the effect on climate of slow changes in the tilt of the Earth 's axis and shape of the Earth's orbit around the sun (see Milankovitch cycles ). These orbital changes modify the total amount of sunlight reaching the Earth by up to 25% at mid-latitudes (from 400 to 500 W/ (m 2) at latitudes of 60 degrees).

On the orbital timescale, monsoon precipitation is strongest when eccentricity is maximum. 100-kyr cycles of precipitation were forced by Northern hemisphere solar radiation, rather than the Antarctic ice sheet.
WebOct 17, 1997 · Simulations with climate models have indicated that the orbital changes caused an increase in the amplitude of the seasonal cycle of solar radiation in the Northern Hemisphere, enhanced summertime land-ocean temperature contrasts, and thereby strengthened northern summer monsoons ( 1-5 ). WebDec 1, 2024 · The COCO and eCOCO sedimentation rate maps of the MS and Zr/Al series reveal an average sedimentation rate of 1.2–1.9 cm/kyr, with a null hypothesis of no orbital forcing at a 99.9% confidence (Fig. 5 and Fig. S3). Taken together, we consider that the optimal mean sedimentation rate of the Qiongzhusi Fm of the Dongxihe section ranges …
