Superensemble regional climate modeling for the western United States

Creator:: Mote, Philip W., Allen, Myles R., Jones, Richard G., Li, Sihan, Mera, Roberto, Rupp, David E., Salahuddin, Ahmed, and Vickers, Dean
Abstract:: Computing resources donated by volunteers have generated the first superensemble of regional climate model results, in which the Hadley Centre Regional Model, version 3P (HadRM3P), and Hadley Centre Atmosphere Model, version 3P (HadAM3P), were implemented for the western United States at 25-km resolution. Over 136,000 valid and complete 1-yr runs...

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...

Global Patterns of Diapycnal Mixing from Measurements of the Turbulent Dissipation Rate

Creator:: Waterhouse, Amy F., MacKinnon, Jennifer A., Nash, Jonathan D., Alford, Matthew H., Kunze, Eric, Simmons, Harper L., Polzin, Kurt L., St. Laurent, Louis C., Sun, Oliver M., Pinkel, Robert, Talley, Lynne D., Whalen, Caitlin B., Huussen, Tycho N., Carter, Glenn S., Fer, Ilker, Waterman, Stephanie, Naveira Garabato, Alberto C., Sanford, Thomas B., and Lee, Craig M.
Abstract:: The authors present inferences of diapycnal diffusivity from a compilation of over 5200 microstructure profiles. As microstructure observations are sparse, these are supplemented with indirect measurements of mixing obtained from (i) Thorpe-scale overturns from moored profilers, a finescale parameterization applied to (ii) shipboard observations of upper-ocean shear, (iii) strain as...

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...

Near-Surface Density Currents Observed in the Southeast Pacific Stratocumulus-Topped Marine Boundary Layer

Creator:: Wilbanks, Matt C., Yuter, Sandra E., de Szoeke, Simon P., Brewer, W. Alan, Miller, Matthew A., Hall, Andrew M., and Burleyson, Casey D.
Abstract:: Density currents (i.e., cold pools or outflows) beneath marine stratocumulus clouds are characterized using 30 days of ship-based observations obtained during the 2008 Variability of American Monsoon Systems (VAMOS) Ocean–Cloud–Atmosphere–Land Study Regional Experiment (VOCALS-REx) in the southeast Pacific. An air density increase criterion applied to the Improved Meteorological (IMET) sensor...

Abstract:: The diurnal variability and the environmental conditions that support the moisture resurgence of MJO events observed during the Cooperative Indian Ocean Experiment on Intraseasonal Variability (CINDY)/DYNAMO campaign in October–December 2011 are investigated using in situ observations and the cloud-resolving fully air–ocean–wave Coupled Ocean–Atmosphere Mesoscale Prediction System (COAMPS). Spectral density and...

Oceanic Turbulent Energy Budget using Large-Eddy Simulation of a Wind Event during DYNAMO

Creator:: Hoecker-Martínez, Martin S., Smyth, William D., and Skyllingstad, Eric D.
Abstract:: The dominant processes governing ocean mixing during an active phase of the Madden–Julian oscillation are identified. Air–sea fluxes and upper-ocean currents and hydrography, measured aboard the R/V Revelle during boreal fall 2011 in the Indian Ocean at 0°, 80.5°E, are integrated by means of a large-eddy simulation (LES) to infer...

The geography of semidiurnal mode-1 internal-tide energy loss

Creator:: Kelly, S. M., Jones, N. L., Nash, J. D., and Waterhouse, A. F.
Abstract:: The semidiurnal mode-1 internal tide receives 0.1-0.3 TW from the surface tide and is capable of propagating across ocean basins. The ultimate fate of mode-1 energy after long-distance propagation is poorly constrained by existing observations and numerical simulations. Here, global results from a two-dimensional semi-analytical model indicate that topographic scattering...

Wave-Breaking Turbulence in the Ocean Surface Layer

Creator:: Thomson, Jim, Schwendeman, Michael S., Zippel, Seth F., Moghimi, Saeed, Gemmrich, Johannes, and Rogers, W. Erick
Abstract:: Observations of winds, waves, and turbulence at the ocean surface are compared with several analytic formulations and a numerical model for the input of turbulent kinetic energy by wave breaking and the subsequent dissipation. The observations are generally consistent with all of the formulations, although some differences are notable at...
