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 …

Assessing factors contributing to the changes in historical temperature extremes and investigating future changes in extreme events
… strategies (at regional or site-specific scales) towards the management of catastrophe caused by the extremes. In this dissertation, the observed spatial and temporal variations in temperature extremes are first analyzed at a hemispheric scale based on the newly developed HadEX3 dataset; …

The response of moist convection and the atmospheric general circulation to climate warming
In this thesis, the response of atmospheric circulations to changes in surface temperature is investigated. Both cloud-scale and planetary-scale circulations are considered, and a number of different theoretical and numerical tools are employed. First, mechanisms maintaining the thermal …

Amundsen Sea sea-ice variability, atmospheric circulation, and spatial variations in snow isotopic composition from new West Antarctic firn cores
… loss, glacier acceleration, surface warming) due largely to the influence of the marine environment. WAIS is particularly vulnerable to largescale atmospheric dynamics that remotely influence the transport of marine aerosols to the ice sheet. Understanding seasonal- to decadal-scale changes in the …

Hydroclimate Drivers and Atmospheric Dynamics of Floods
… the physical mechanisms of long-duration and large-peak flood events that can evoke substantial damages to properties and infrastructure systems. These studies also fell short of fully assessing the interactions of coupled ocean-atmosphere and land dynamics which are capable of forcing …

Precipitation prediction over High Mountain Asia using Gaussian processes
… the few available measurements or to downscale and bias-correct precipitation outputs from models have several limitations, especially over complex terrain. Future precipitation is even more challenging to predict. Improving predictions will enhance hydrological modelling, strengthen water …

On the observed and simulated responses of the extratropical atmosphere to surface thermal forcing
… system have wide-ranging impacts on the large-scale and local patterns of climate and weather variability from one region of the globe to another. Improvements in the resolution of satellite observations and numerical models over the past decade have led to a series of advances in …

Arctic Cloud, Radiation and their Interactions with Sea Ice
… sea ice changes from seasonal to interannual scales utilizing an integrative analysis. The reanalysis product is a convenient and necessary tool in the Arctic climate study. However, their uncertainties should be quantified first before utilizing these reanalyses in Arctic climate studies. …

Mid- to Late Holocene flood reconstruction from two varved sediment profiles of pre-alpine Lake Ammersee (Southern Germany)
… radiative forcing under global warming enhances atmospheric water-holding capacity and is expected to increase the likelihood of strong floods. In addition, natural climate variability affects the frequency and magnitude of these events on annual to millennial time-scales. Particularly in the …

The influence of Arctic sea-ice loss on mid-latitude weather and climate: exploring sensitivities and mechanisms
… using an intermediate complexity global circulation model, IGCM4. Such models are useful because they are complex enough to simulate a variety of important processes, but are relatively simple and computationally fast compared to full complexity state-of-the-art climate models. This helps …
