The Impact of ENSO on Atmospheric Intraseasonal Variability as Inferred from Observations and GCM Simulations
The impact of the El Niño–Southern Oscillation (ENSO) on the atmospheric intraseasonal variability in the North Pacific is assessed, with emphasis on how ENSO modulates midlatitude circulation anomalies associated with the Madden–Julian oscillation (MJO) in the Tropics and the westward-traveling patterns (WTP) in high latitudes. The database for this study consists of the output of a general ci...
متن کاملGcm Simulations of Martian Methane
Introduction: The spectroscopic detection of methane in the atmosphere of Mars is the first observation of an organic compound on that planet [1-3]. CH4 has a lifetime of a few centuries, which suggests a young or current source. On the other hand, this lifetime is long enough for the atmospheric circulation to yield a uniform distribution of CH4 across the planet, which is not what is observed...
متن کاملA Systematic Relationship between Intraseasonal Variability and Mean State Bias in AGCM Simulations
Systematic relationships between aspects of intraseasonal variability (ISV) and mean state bias are shown in a number of atmospheric general circulation model (AGCM) simulations. When AGCMs are categorized as either strong ISV or weak ISV models, it is shown that seasonal mean precipitation patterns are similar among models in the same group but are significantly different from those of the oth...
متن کاملIntraseasonal variability in the Makassar Strait thermocline
Intraseasonal variability [ISV] in the Makassar Strait thermocline is examined through the analysis of along-channel flow, regional sea level anomaly and wind fields from January 2004 through November 2006. The dominant variability of 45–90 day in the Makassar Strait along-channel flow is horizontally and vertically coherent and exhibits vertical energy propagation. The majority of the Makassar...
متن کاملEddy Influences on Hadley Circulations: Simulations with an Idealized GCM
An idealized GCM is used to investigate how the strength and meridional extent of the Hadley circulation depend on the planet radius, rotation rate, and thermal driving. Over wide parameter ranges, the strength and meridional extent of the Hadley circulation display clear scaling relations with regime transitions, which are not predicted by existing theories of axisymmetric Hadley circulations....
