Tracking the Strength of the Walker Circulation With Stable Isotopes in Water Vapor

Creator:: Dee, Sylvia G., Nusbaumer, Jesse, Bailey, Adriana, Russell, James M., Lee, Jung-Eun, Konecky, Bronwen, Buenning, Nikolaus H., and Noone, David C.
Abstract:: General circulation models (GCMs) predict that the global hydrological cycle will change in response to anthropogenic warming. However, these predictions remain uncertain, in particular, for precipitation (Intergovernmental Panel on Climate Change, 2013, https://doi .org/10.1017/CB09781107415324.004). Held and Soden (2006, https://doi.org/10.1175/JCLI3990.1) suggest that as lower tropospheric water vapor concentration increases in a...

The LatMix Summer Campaign: Submesoscale Stirring in the Upper Ocean

Creator:: Shcherbina, Andrey Y., Sundermeyer, Miles A., Kunze, Eric, D'Asaro, Eric, Badin, Gualtiero, Birch, Daniel, Brunner-Suzuki, Anne-Marie E. G., Callies, Jörn, Kuebel Cervantes, Brandy T., Claret, Mariona, Concannon, Brian, Early, Jeffrey, Ferrari, Raffaele, Goodman, Louis, Harcourt, Ramsey R., Klymak, Jody M., Lee, Craig M., Lelong, M.-Pascale, Levine, Murray D., Lien, Ren-Chieh, Mahadevan, Amala, McWilliams, James C., Molemaker, M.

Shafer, Tandon, Amit, Taylor, John R., Terray, Eugene A., Thomas, Leif N., and Ledwell, James R.
Abstract:: Lateral stirring is a basic oceanographic phenomenon affecting the distribution of physical, chemical, and biological fields. Eddy stirring at scales on the order of 100 km (the mesoscale) is fairly well understood and explicitly represented in modern eddy-resolving numerical models of global ocean circulation. The same cannot be said for...

Validation of IMERG Precipitation in Africa

Creator:: Dezfuli, Amin K., Ichoku, Charles M., Huffman, George J., Mohr, Karen I., Selker, John S., van de Giesen, Nick, Hochreutener, Rebecca, and Annor, Frank O.
Abstract:: Understanding of hydroclimatic processes in Africa has been hindered by the lack of in situ precipitation measurements. Satellite-based observations, in particular, the TRMM Multisatellite Precipitation Analysis (TMPA) have been pivotal to filling this void. The recently released Integrated Multisatellite Retrievals for GPM (IMERG) project aims to continue the legacy of...

Tropical origins of North and South Pacific decadal variability

Creator:: Shakun, Jeremy D. and Shaman, Jeffrey
Abstract:: The origin of the Pacific Decadal Oscillation (PDO), the leading mode of sea surface temperature variability for the North Pacific, is a matter of considerable debate. One paradigm views the PDO as an independent mode centered in the North Pacific, while another regards it as a largely reddened response to...

A Statistical Method for Generating Temporally Downscaled Geochemical Tracers in Precipitation

Creator:: Finkenbiner, Catherine E., Good, Stephen P., Allen, Scott T., Fiorella, Richard P., and Bowen, Gabriel J.
Abstract:: Sampling intervals of precipitation geochemistry measurements are often coarser than those required by fine-scale hydrometeorological models. This study presents a statistical method to temporally downscale geochemical tracer signals in precipitation so that they can be used in high-resolution, tracer-enabled applications. In this method, we separated the deterministic component of the...

Ocean surface wind divergence and vorticity co-variability and statistical differences between QuikSCAT and ERA5

Creator:: Jacobs, Robert
Abstract:: I examine the strong co-variability between the surface divergence and vorticity and how it varies with latitude in the Pacific Ocean using surface vector winds from reanalysis and satellite scatterometer observations. This analysis was motivated in part by a significant correlation between divergence and vorticity over the global oceans that...

Mechanisms of convective cloud organization by cold pools over tropical warm ocean during the AMIE/DYNAMO field campaign

Creator:: Feng, Zhe, Hagos, Samson, Rowe, Angela K., Burleyson, Casey D., Martini, Matus N., and de Szoeke, Simon P.
Abstract:: This paper investigates the mechanisms of convective cloud organization by precipitation-driven cold pools over the warm tropical Indian Ocean during the 2011 Atmospheric Radiation Measurement (ARM) Madden-Julian Oscillation (MJO) Investigation Experiment/Dynamics of the MJO (AMIE/DYNAMO) field campaign. A high-resolution regional model simulation is performed using the Weather Research and Forecasting...

Coastal ocean variability inferred from high resolution models : two case studies

Creator:: Mauch, Matthew L.
Abstract:: In this thesis, high resolution ocean models are used to evaluate and forecast coastal ocean variability in two different applications. In the first study, the 2-km resolution ocean circulation model for the Eastern Bering Sea is utilized to understand whether slope-interior exchange along the path of the Aleutian North Slope...

Interannual variability of Great Lakes ice cover and its relationship to NAO and ENSO

Creator:: Bai, Xuezhi, Wang, Jia, Sellinger, Cynthia, Clites, Anne, and Assel, Raymond
Abstract:: The impacts of North Atlantic Oscillation (NAO) and El Niño–Southern Oscillation (ENSO) on Great Lakes ice cover were investigated using lake ice observations for winters 1963–2010 and National Centers for Environmental Prediction reanalysis data. It is found that both NAO and ENSO have impacts on Great Lakes ice cover. The...

Evidence for Strengthening Hadley Cells and a Westward Expansion of the Walker Circulation from Assimilation of Paleoclimate Proxy Data

Creator:: Horlick, Kaleb A.
Abstract:: A synthesis of over 2000 paleoclimate proxy records is performed via a data assimilation framework that expands upon previous efforts by implementing a suite of physically-based proxy system models, and which provides the first example of an observationally independent, multi-seasonal (DJFM, JJAS) paleoclimate reanalysis. This methodology is contrasted against previous...
