Motivated by findings that energetically consistent subgrid dissipation schemes can improve eddy-permitting ocean simulations, this work investigates the impact of the subgrid dissipation scheme on low-resolution atmospheric dynamical cores. A k[...]texto impreso
A cessation of the Atlantic meridional overturning circulation (AMOC) significantly reduces northward oceanic heat transport. In response to anomalous freshwater flux, this leads to the classic 'bipolar see-saw' pattern of northern cooling and s[...]texto impreso
Substantial increases in the atmospheric concentration of well-mixed greenhouse gases (notably CO2), such as those projected to occur by the end of the 21st century under large radiative forcing scenarios, have long been known to cause an accele[...]texto impreso
Pinto, Joaquim G. ; Gómara Cardalliaguet, Iñigo ; Masato, Giacomo ; Dacre, Helen F. ; Woollings, Tim ; Caballero, Rodrigo | American Geophysical Union | 2014-12-27Some recent winters in Western Europe have been characterized by the occurrence of multiple extratropical cyclones following a similar path. The occurrence of such cyclone clusters leads to large socio-economic impacts due to damaging winds, sto[...]texto impreso

Bolgiani, Pedro ; Santos Muñoz, Daniel ; Fernández González, Sergio ; Sastre Marugán, Mariano ; Valero Rodríguez, Francisco ; Martín, María Luisa | American Geophysical Union | 2020-07-27Microbursts are meteorological phenomena in the lower troposphere which can produce damaging surface winds and pose a severe risk to aircraft flying close to the ground.

The systematic representation of models in steps, or hierarch[...]texto impreso
As part of the Coupled Model Intercomparison Project, integrations with a common design have been undertaken with eleven different climate models to compare the response of the Atlantic thermohaline circulation ( THC) to time-dependent climate c[...]texto impreso
We develop a topological model of ball lightning which explains its stability by the coupling of an air ball to a magnetic knot, a magnetic field with linked magnetic lines. Assuming that currents flow inside the ball, along short-circuited link[...]texto impreso

P. ; Valero Rodríguez, Francisco | American Geophysical Union | 2005-04-27The spatial patterns of surface air-temperature variations in the period 1000 to 2100, simulated with the ECHO-G atmosphere-ocean coupled model, are analyzed. The model was driven by solar, volcanic and greenhouse gas forcing. The leading mode o[...]texto impreso

A dominant[...]texto impreso
Ábalos Álvarez, Marta ; Polvani, Lorenzo ; Calvo Fernández, Natalia ; Kinnison, Douglas ; Ploeger, Felix ; Randel, William ; Solomon, Susan | American Geophysical Union | 2019-03-16It has recently been recognized that, in addition to greenhouse gases, anthropogenic emissions of ozone-depleting substances (ODS) can induce long-term trends in the Brewer-Dobson circulation (BDC). Several studies have shown that a substantial [...]texto impreso
