However, we now know that climate change is already affecting
regional circulation patterns and by extension helping to shape local extreme weather.

Variations in
regional precipitation and temperature have long been determined to be strongly correlated with natural oceanic - atmospheric
circulation patterns, or oscillations.
Jiacan has worked on several projects on climate dynamics, including the response of large - scale
circulations in the warming climate, its effects on
regional weather
patterns and extreme events, tropical influence on mid-latitude weather, and dynamical mechanisms of sub-seasonal variability of mid-latitude jet streams.
-LSB-...] Variations in

Resulting changes in the atmospheric temperature structure, including from surface dimming, in turn affect
regional circulation and precipitation
patterns.
Yet, we explained there is also reasonable basis for concern that a warming world may at least temporarily increase tornado damage including the fact that oceans are now warmer, and
regional ocean
circulation cycles such as La Nina / El Nino
patterns in the Pacific which affect upper atmospheric conditions appear to becoming more chaotic under the influence of climate change.
«A climate
pattern may come in the form of a regular cycle, like the diurnal cycle or the seasonal cycle; a quasi periodic event, like El Niño; or a highly irregular event, such as a volcanic winter... A mode of variability is a climate
pattern with identifiable characteristics, specific
regional effects, and often oscillatory behavior... the mode of variability with the greatest effect on climates worldwide is the seasonal cycle, followed by El Niño - Southern Oscillation, followed by thermohaline
circulation.»
«The authors write that North Pacific Decadal Variability (NPDV) «is a key component in predictability studies of both
regional and global climate change,»... they emphasize that given the links between both the PDO and the NPGO with global climate, the accurate characterization and the degree of predictability of these two modes in coupled climate models is an important «open question in climate dynamics» that needs to be addressed... report that model - derived «temporal and spatial statistics of the North Pacific Ocean modes exhibit significant discrepancies from observations in their twentieth - century climate... conclude that «for implications on future climate change, the coupled climate models show no consensus on projected future changes in frequency of either the first or second leading
pattern of North Pacific SST anomalies,» and they say that «the lack of a consensus in changes in either mode also affects confidence in projected changes in the overlying atmospheric
circulation.»»
Furthermore,
regional atmospheric
circulation patterns were linked to
patterns of cloudiness.
«Most
circulation patterns on Earth are much wider than they are high, with the ratio height / length being in the order of 10 - 2 for hurricanes and down to 10 - 3 and below in larger
regional circulations.
Scientists have recently observed major changes in these glaciers: several have broken up at the ocean end (the terminus), and many have doubled the speed at which they are retreating.2, 5 This has meant a major increase in the amount of ice and water they discharge into the ocean, contributing to sea - level rise, which threatens low - lying populations.2, 3,5 Accelerated melting also adds freshwater to the oceans, altering ecosystems and changing ocean
circulation and
regional weather
patterns.7 (See Greenland ice sheet hotspot for more information.)
Accelerated melting also adds more freshwater to the oceans, altering ecosystems and changing ocean
circulation and
regional weather
patterns.9
The North American
Regional Reanalysis (NARR) displays a diurnal
circulation pattern centered over Northern Texas that links together
regional patterns in the diurnal cycles of assimilated precipitation.
The General
Circulation Models (GCM) driving the
regional models chosen are rated in the top 25 %, according to a performance evaluation of CMIP5 models carried out by Perez et al. (2014), in their ability to reproduce spatial
patterns and climate variability over the north - east Atlantic region, that is the most influential on the European weather
patterns.
It is better to look at
regional level
pattern as they follow general
circulation patterns in conjenction with natural in - built cyclic variations.
They first sorted the data into
regional patterns, and then compared the temporal behavior of these
patterns to common historical climate indices — such as well - known
patterns of atmospheric
circulation, sea surface temperatures, or even large - scale warming.
Jiacan has worked on several projects on climate dynamics, including the response of large - scale
circulations in the warming climate, its effects on

patterns and extreme events, tropical influence on mid-latitude weather, and dynamical mechanisms of sub-seasonal variability of mid-latitude jet streams.
The difference is that the warming of the Western Antarctica Peninsula was known and is easily explained through atmospheric
circulation dynamics —
regional warm air advection
patterns.
A recent study on the North Pacific
circulation patterns over the past 1.2 million years determined that sea ice on coastal areas can be an important factor in ocean
circulation, therefore influencing climate at global and
regional levels.
