Sentences with phrase «zonal anomaly»

Not much «blue» in the Arctic (not with urban heat islands or heavy industries) with a mean zonal anomaly of +4 C near the Pole.

Under rapid greenhouse warming, the different parts of the planet have warmed at very different rates, leading to the scatter in the zonal anomalies since 1980.

The zonal anomalies map for September of 2014 showed no latitudinal zone experiencing cooler than 20th Century average conditions.

The underlying issue is this: While the planet was subject primarily to natural changes, the different parts of the planet were warming and cooling at similar rates, thus the zonal anomalies run fairly parallel.

Zonal Anomalies Reveal Extraordinary Polar Amplification, Tell - Tale of Southern Ocean Heat Sink

Along with the negative AO index, we've seen an increased frequency of the the Arctic Dipole Anomaly, whereby the deep polar closed low that normally keeps the Arctic air contained is split into a pressure zones on both sides of the pole (i.e. a dipole) creating zonal winds across the Arctic shunt both cold air (and ice) more vigorously out of the Arctic.

The improved simulation of ENSO amplitude is mainly due to the reasonable representation of the thermocline and thermodynamic feedbacks: On the one hand, the deeper mean thermocline results in a weakened thermocline response to the zonal wind stress anomaly, and the looser vertical stratification of mean temperature leads to a weakened response of anomalous subsurface temperature to anomalous thermocline depth, both of which cause the reduced thermocline feedback in g2; on the other hand, the alleviated cold bias of mean sea surface temperature leads to more reasonable thermodynamic feedback in g2.

These anomalies modulate high - latitude zonal winds, with El Niño (La Niña) conditions causing reduced (enhanced) zonal wind speeds and subsequent reduced (enhanced) summer sea salt deposition at LD.

Hawkins and Jones (2013) focused on one small aspect of Callendar's work: his compilation of World Weather Records station temperature data into zonal and global temperature anomalies, in effect, delimiting Callendar, whose contribution was much more diverse, as a sort of John the Baptist of temperature accountancy, merely preparing the way for Phil Jones.

The lack of zonal correlation between the P * — E * change and the simple thermodynamic scaling (dashed blue line in Fig. 2) further emphasizes that the «wet gets wetter» mechanism breaks down for anomalies from the zonal mean.

These zonal gradients of SST result in an anomaly in circulation of two Walker cells on the tropical Pacific, with a humid region in the Eastern and the Western Pacific.

Interactions between externally - forced climate signals from sunspot peaks and the internally - generated Pacific Decadal and North Atlantic Oscillations «When the PDO is in phase with the 11 year sunspot cycle there are positive SLP anomalies in the Gulf of Alaska, nearly no anomalous zonal SLP gradient across the equatorial Pacific, and a mix of small positive and negative SST anomalies there.

Fig 2.3 Dynamics of the detrended global temperature anomaly (dT) and the Zonal Atmospheric Circulation Index (zonal ACI)(see text for detaZonal Atmospheric Circulation Index (zonal ACI)(see text for detazonal ACI)(see text for details).

Top: zonal (west - to - east) wind anomalies at 250mb during 2013.

These anomalies modulate high latitude zonal winds, with El Niño (La Niña) conditions causing reduced (enhanced) zonal wind speeds and subsequently, reduced (enhanced) summer sea salt deposition at LD.»

This in turn can explain why zonal wind stress and bottom pressure anomalies around Antarctica tend to be anticorrelated in both GRACE and ECCO results.

The first principal component is significantly correlated with the SAM index (the first principal component of sea - level - pressure or 500 - hPa geopotential heights for 20u S — 90u S), and the second principal component reflects the zonal wave - 3 pattern, which contributes to the Antarctic dipole pattern of sea - ice anomalies in the Ross Sea and Weddell Sea sectors.

A mechanism is presented by which eddy heat and momentum transport couple to retard motion of the jet, slowing its meridional variation and thereby extending the persistence of zonal index and annular mode anomalies.
