1) Model operates used
step one (Delworth mais aussi al. 2006) presenting a restricted-regularity dynamical center (Lin 2004) having a lateral resolution around 2° latitude and twenty-four vertical levels. The latest atmospheric design was combined so you’re able to good slab sea having spatially uniform breadth. Four getup users which have given water deepness off dos.cuatro, 6, 12, 24, and you will fifty yards is actually reviewed inside investigation. This new design try forced because of the seasonally differing insolation with zero eccentricity and you may ° obliquity, and is manage to possess twenty years, enough to gather on the a constant climatology. New model climatology are obtained from the last 5 years away from the fresh new integrations.
2) Efficiency
The seasonal migration of the ITCZ off the equator has a larger amplitude for shallower ocean depths (Fig. 8) and PPenny reaches as far as 21° how many users on Plenty of Fish vs OkCupid? in the 2.4-m slab depth run as compared to 3° in the 50-m slab depth run. This behavior is expected because the adjustment time scale of a 50-m-deep ocean to solar heating is on the order of one year (Donohoe 2011) as compared to weeks for 2.4-m-deep ocean. Thus, the SSTs barely adjust to the seasonally varying insolation in the 50-m run while the maximum SST moves seasonally with the insolation in the 2.4-m run.
(top) Regular directory of rain centroid and you can atmospheric heat transportation along the equator throughout the slab water aquaplanet simulations with every simulator (ocean breadth) provided by an alternate colour. This new seasonal assortment is twice the fresh new amplitude of annual harmonic of each varying and the mountain of the line ‘s the regression coefficient of one’s monthly analysis. The new black asterisks will be monthly observations plus the solid black line ‘s the regular selection of the brand new findings. (bottom) Due to the fact at the best, however for rain centroid and you can tropical SST gradient.

The fresh new regular range is double the fresh new amplitude of the annual harmonic each and every changeable and hill of one’s line is the regression coefficient of monthly analysis. The black colored asterisks certainly are the month-to-month findings as well as the good black line ‘s the seasonal selection of this new findings. (bottom) As the at ideal, however for rain centroid and you can tropical SST gradient.

The seasonal variety is actually double the brand new amplitude of annual harmonic each and every varying in addition to hill of your own line ‘s the regression coefficient of month-to-month study. Brand new black colored asterisks will be the month-to-month findings therefore the good black colored range ‘s the seasonal a number of this new observations.

The seasonal amplitude of AHTEQ also decreases with increasing ocean depth, from 11.6 PW in the 2.4-m run to 0.5 PW in the 50-m run. In the shallow ocean run, the SSTs respond rapidly to the seasonally varying insolation, heating up over the summer hemisphere and subsequently fluxing energy upward (via turbulent and longwave fluxes) to the adjacent atmosphere to drive seasonal variations in AHTEQ; in the 2.4-m run ?SHF? is nearly in phase with the insolation (11-day lag) and has a seasonal amplitude of 11.6 PW. In contrast, the solar heating of the ocean makes a minimal impact on ocean temperatures in the deep ocean runs due to the large heat capacity of the ocean. In fact, SWABS is the only source of seasonal atmospheric heating in the 50-m run and the atmosphere loses energy to the ocean during the warm season; in the 50-m run ?SHF? is nearly antiphased with the insolation (192-day lag) and has a seasonal amplitude of 3.7 PW.
