The newest design integrations are executed toward Geophysical Water Figure Research (GFDL) Atmospheric Design version dos

1) Model works utilized

step one (Delworth ainsi que al. 2006) offering a limited-volume dynamical center (Lin 2004) having a horizontal quality around dos° latitude and you may twenty four straight account. New atmospheric design is coupled so you can good slab ocean with spatially uniform depth. Four getup professionals that have recommended water deepness regarding dos.cuatro, 6, a dozen, 24, and you can fifty meters are examined in this investigation. The newest design is forced of the seasonally different insolation that have zero eccentricity and you may ° obliquity, and that’s work at for 20 years, sufficient to converge into the a reliable climatology. The fresh new design climatology are obtained from the final 5 years from the new integrations.

2) Abilities

The seasonal migration of the ITCZ off the equator has a larger amplitude for shallower ocean depths (Fig. 8) and PCent reaches as far as 21° 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) Seasonal a number of rain centroid and you can atmospheric heat transportation along side equator regarding slab water aquaplanet simulations with each simulator (sea depth) given by a different colour. The seasonal assortment was twice brand new amplitude of yearly harmonic of every varying and mountain of the line is the regression coefficient of your own monthly studies. The brand new black colored asterisks are definitely the month-to-month observations in addition to solid black colored line ‘s the seasonal list of new observations. (bottom) Because at most useful, but for precipitation centroid and exotic SST gradient.

(top) Seasonal list of precipitation centroid and atmospheric temperature transportation along the equator on the slab water aquaplanet simulations with each simulation (ocean breadth) supplied by a new colour. The newest regular diversity are twice the latest amplitude of your own annual harmonic of every adjustable plus the slope of line is the regression coefficient of the monthly research. The new black colored asterisks will be month-to-month observations additionally the solid black colored range ‘s the seasonal a number of new findings. (bottom) While the from the ideal, however for precipitation centroid and you can tropical SST gradient.

(top) Regular set of rain centroid and atmospheric temperature transport over the equator in the slab sea aquaplanet simulations with every simulator (ocean depth) supplied by another type of color. This new regular diversity are twice brand new amplitude of your own annual harmonic of every variable therefore the hill of the range ‘s the regression coefficient of one’s monthly studies. The fresh new black asterisks are definitely the month-to-month findings and also the good black colored line is the seasonal a number of the observations. gay hookup app for iphone (bottom) Given that within most readily useful, but also for rain centroid and you may warm SST gradient.

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.
