Interactions between clouds and atmospheric circulation in the extratropics
… explores the connections between clouds and atmospheric circulation in extratropical regions. In particular, we investigate the impacts of clouds and their uncertainties on atmospheric circulation and its response to global warming. We find that clouds have very substantial effects both on …

Orographic Gravity Wave Drag and the Large Scale Atmospheric Circulation
… of this modelling is concerned with the general circulation, which is affected by orographic gravity waves and the drag force that they exert on the mean flow. The effects of Orographic Gravity Wave Drag (OGWD) are what is explored in this thesis. By experimenting on the OGWD forcing in an …

Studies of wave-mean interaction relevant to the middle atmospheric circulation
… Lagrangian-mean}$ meridional circulation is not always negligible. A sharp-edge model on the polar y-plane is introduced in Chapter 5 to study Rossby waves associated with the polar vortex. Results show that the vortex edge can support both free travelling and forced Rossby …

Atmospheric circulation and the surface mass balance in a regional climate model of Antarctica
… principal region of radiative energy deficit and atmospheric cooling. An assessment of regional climate model HIRHAM is presented. The simulations are generated with the HIRHAM model, which is modified for Antarctic applications. With a horizontal resolution of 55km, the model has been run for the …

Variability in spring snowpack and winter atmospheric circulation pattern frequencies in the Peace River Basin
… were associated with changes in prevailing atmospheric circulation as shown by the decrease of snow producing types resulting from the application of the Kirchhofer climate classification technique to surface pressure and 50 kPa height data. The lack of spring ice-jam flooding in the …

Changes in monsoonal precipitation and atmospheric circulation during the Holocene reconstructed from stalagmites from Northeastern India
… decadal to centennial failures resulting from atmospheric changes. The period of maximum rainfall and enhanced seasonality corresponds to the Holocene Thermal Optimum observed in Europe. After a phase of rather stable conditions, 4.5 kyr ago, the strengthening ENSO system dominated the ISM. …

The Impact of a Warmer Climate on Atmospheric Circulation with Implications for the Asian Summer Monsoon
… tropical and high latitude warming on regional atmospheric circulation using GISS global climate model simulations of the Pliocene and sensitivity tests. Chapter 1 discusses the initial approach used to investigate how a warmer climate impacts regional atmospheric circulation. A general …

The impact of tropical sea surface temperature perturbations on atmospheric circulation over north Canada and Greenland
… of the trends over NCG and understand how circulation in this region responds to imposed tropical SST perturbations. The eddy 200 hPa geopotential height (Z200) trends over NCG are assessed in a number of different datasets and compared to the response of eddy Z200 over NCG to imposed …

Interannual variability in cloudiness, sea surface temperature, and atmospheric circulation over the midlatitude North Pacific during summer
Large-scale interannual and interdecadal variability in surface-observed marine stratiform cloud (MSC) amount and sea surface temperature (SST) are closely coupled over the central North Pacific during summer. Increased (decreased) MSC amount occurs with decreased (increased) SST, resulting from …

The Relationship Between Atmospheric Circulation Patterns And Water Surface Elevation In Devils Lake, North Dakota: 1965-2010
… study is to examine the relationship between atmospheric circulation anomalies and historical water surface elevation fluctuations. Two independent datasets are used: the Spatial Synoptic Classification and the NCEP/NCAR Reanalysis datasets of precipitable water and 700 mb (hPa) geopotential …

The detection and prediction of climate change in Ireland using an automated classification of atmospheric circulation patterns
… what is steering this change in climate. A circulation-type catalogue for Ireland has been constructed from National Centers for Environmental Prediction (NCEP) Reanalysis data, to objectively classify atmospheric circulation patterns. It is thus possible to determine to what extent the …

The effect of topography on the Martian atmospheric circulation and determining Pluto's atmospheric thermal structure from stellar occultations
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 …

Amundsen Sea sea-ice variability, atmospheric circulation, and spatial variations in snow isotopic composition from new West Antarctic firn cores

Atmospheric circulation and sea surface temperature anomalies during the dry summers of 2001/02, 2002/03 and 2003/04 in Southern Africa
Drought is a phenomenon associated with the lack or shortage of water. It means less than normal or no water is available. It primarily originates from lack of precipitation. Lack of precipitation leads to depletion of storage of I. soil moisture that results in dry land crop failure and dying-off …
