An Analysis of the Effect of Topography on the Martian Hadley Cells [PDF]

open access: yesJournal of the Atmospheric Sciences, 2010
Abstract Previous work with Mars general circulation models (MGCMs) has shown that the north–south slope in Martian topography causes asymmetries in the Hadley cells at equinox and in the annual average. To quantitatively solve for the latitude of the dividing streamline and poleward boundaries of the cells, the Hadley cell model of ...

The Sensitivity of the Hadley Circulation to Past and Future Forcings in Two Climate Models

open access: yes, 2004
A comparison is made of the Hadley cell response to altered external forcing and climatic boundary conditions in two different climate models. The experiments performed cover past and future climatic forcings that range from the last glacial maximum (LGM)

Arctic amplification and modal variability of the Hadley cell on interannual timescales

open access: yesEnvironmental Research: Climate
The Equator-to-Pole temperature gradient sustains the zonally axisymmetric Hadley-type thermally direct circulations and the midlatitude thermally driven jet, as well as baroclinicity.

Energetic Constraints on the ITCZ Position in Idealized Simulations With a Seasonal Cycle

open access: yesJournal of Advances in Modeling Earth Systems, 2018
The atmospheric energy budget has recently been shown to provide powerful constraints on the position and shifts of the zonal and annual mean intertropical convergence zone (ITCZ), which lies close to the latitude of zero vertically integrated energy ...

On the comparisons of tropical relative humidity in the lower and middle troposphere among COSMIC radio occultations and MERRA and ECMWF data sets [PDF]

open access: yesAtmospheric Measurement Techniques, 2015
The spatial variability of the tropical tropospheric relative humidity (RH) throughout the vertical extent of the troposphere is examined using Global Positioning System Radio Occultation (GPSRO) observations from the Constellation Observing System for ...

Structural changes in the interannual variability of extreme autumn precipitation in eastern Spain and the weakening of synoptic forcing

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Total autumn precipitation in eastern Spain remains stable between 1950 and 2024, masking a substantial internal redistribution between ordinary and extreme rainfall. While torrential precipitation (Rp95) increases and ordinary precipitation (Ro) decreases, the extreme contribution index (Cext) shows a significant positive trend and a structural shift ...

What Speleothems Tell Us about Long-Term Rainfall Oscillation throughout the Holocene on a Planetary Scale

open access: yesJournal of Marine Science and Engineering, 2021
Within the context of anthropogenic warming, rainfall oscillations may induce especially important societal impacts worldwide. In this article, we propose to study potential underlying mechanisms related to precipitation changes on a planetary scale by ...

Spontaneous zonal symmetry breaking of tropical rain belt

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Precipitable‐water snapshots show how a sea surface temperature (SST)‐forced tropical rain belt can remain zonally elongated or spontaneously reorganize into a localized convective cluster. The simulations identify the SST conditions favoring this zonal convective self‐aggregation and relate the transition to changes in boundary‐layer circulation and ...

The impact of equilibrating hemispheric albedos on tropical performance in the HadGEM2‐ES coupled climate model

open access: yesGeophysical Research Letters, 2016
The Earth's hemispheric reflectances are equivalent to within ± 0.2 Wm−2, even though the Northern Hemisphere contains a greater proportion of higher reflectance land areas, because of greater cloud cover in the Southern Hemisphere.
