Estuarine plumes are frequently under strong influence of land-derived inputs of organic matter. These plumes have characteristic physical and chemical conditions, and their morphology and extent in the coastal area depends strongly on physical conditions such as river discharge, tides and wind action. In this work we investigate the physical dynamics of the Tagus estuary plume and the CO2. This causes low pressure to spin counterclockwise in the Northern Hemisphere. Clue: the sun rises in the east and sets in the west. a. Clockwise b. Counterclockwise The California Current off the US West Coast is a _____ ocean current while the Gulf Stream off the US East Coast is a _____ ocean current.
The 7th International Conference on Scour and Erosion (ICSE ) was organised by the School of Civil, Environmental and Mining Engineering and the Centre for Offshore Foundation Systems at the University of Western Australia under the guidance of the Technical Committee for Scour and Erosion of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE). This. 1 Introduction. The IPCC's fifth assessment of projected global and regional ocean temperature change [Collins et al., ] is based on global climate models that have relatively coarse (∼ km) ocean and atmosphere resolutions [Flato et al., ].These models are sometimes too coarse to resolve regional dynamics that might affect the uncertainty of climate change projections at.

The Atlantic meridional overturning circulation (AMOC) has a strong influence on climate, so it is important to understand how global warming may affect it. Lozier et al. report initial results from the Overturning in the Subpolar North Atlantic Program (OSNAP) (see the Perspective by Rhein). OSNAP has been measuring the flux of water transported by overturning in the high latitudes in the.

A numerical study of wind forcing in the eastern boundary current system off Portugal. By Carlos N. Lopes da Costa. Download PDF (7 MB) Abstract. Approved for public release; distribution is unlimitedA high resolution, multi-level, primitive equation ocean model is used to examine the response to wind forcing of an idealized, flat-bottomed Author: Carlos N.
Lopes da Costa. The Humboldt Current, also called the Peru Current, is a cold, low-salinity ocean current that flows north along the western coast of South America.
It is an eastern boundary current flowing in the direction of the equator, and extends –1, km (– mi) Humboldt Current is named after the Prussian naturalist Alexander von Humboldt.
The subtropical gyres include eastern boundary current upwelling systems: the Canary Current system in the North Atlantic and Benguela Current System (BCS) in the South Atlantic.
The tropical circulation is predominantly zonal (east–west), including the North Equatorial Countercurrent and the South Equatorial Current, and has a low-latitude.
Long-term automated synoptic observing system (ASOS) data collected from stations over a period of 50 years (–) were analyzed to investigate the distribution of strong winds on the Korean peninsula by utilizing a statistical method.
The Gumbel distribution was used to estimate the wind speed for recurrence periods of 1, 10, 50, 75, and : Jae-Hee Hahm, Ha-Yoon Jeong, Kyung-Hwan Kwak. The Atlantic Water boundary current has two branches in the southern Canada Basin, flowing beneath and counter to the Beaufort Gyre.
The two branches emerge from the Chukchi Borderland due to a series of bifurcations of the single branch that enters the Borderland. The most severe wind storm to have hit the Iberian Peninsula in the 20th century made landfall in the Portuguese coast on February 15th, (Freitas and Dias, ) coming from the SW ().The atmospheric pressure dropped 45 hPa in 18 h over Portugal (Ganho, ), thus it was an explosive cyclogenesis, reaching minimum values of hPa at the Geophysical Institute in Lisbon.

We measured variability in daily supply levels of shore crab megalopae in an estuary on the northwest Portuguese coast, Ria de Aveiro, located in the eastern Atlantic upwelling system. The 5 yr. Abstract.
This chapter describes the major coastal upwelling system on the continental shelves off Iberia (Portugal) and northwest Africa, its physical origin, ecological, cultural, social and economic relevance, and how it has been impacted under. coast are surprising because alongshore wind stress, pre-sumed responsible for macronutrient supply in this Eastern Boundary upwelling system, increases southward over the California Current System (CCS) by a factor of eight [Hickey and Banas,; Ware and Thomson, ].
Greater productivity off the northern coast and near. The NOAA-TM-NMF S-SWFSC rapport () suggests to use the value of C d = with monthly mean data while Santos et al. used C d = for their study of the Moroccan upwelling zone (22°N–33°N).
Over the SMUS region, the maximum wind speed is around 7 m s − compared the meridional component of the wind stress computed online in the IPSL-CM5A-LR climate model to the wind.
The Gulf Stream is the western boundary current of the gyre. The gyre then becomes the North Atlantic Current, which flows across the North Atlantic to Europe. Still flowing in a circular pattern, the current flows south as far as the northwestern coast of Africa, where it is known as the Canary Current—the gyre’s eastern boundary current.
The forcing boundary conditions of the sea-Chicozapote river-El Yucateco lagoon system were set by considering the astronomical tide, winds, and river discharges. The input information into the model as boundary conditions is data obtained from measurements for each season and/or generated by official institutions in the study area [ 56 ].
Coastal upwelling is one of the best studied oceanographic phenomena because of its effects on primary production.
The western coast of the Iberian Peninsula has high biological diversity, mainly due to this primary production. In this study, the response of salinity and temperature to the occurrence of upwelling was analysed at the Ria de Vigo– and Ria de Aveiro–ocean boundary over the.
Somali upwelling system, the fifth in the world, presents some unique features compared with the other major upwelling systems: 1) it is a Western Boundary Upwelling System located.
FEMA provides flood hazard and risk data to help guide mitigation actions. Flood mapping is an important part of the National Flood Insurance Program (NFIP), as it is the basis of the NFIP regulations and flood insurance requirements. FEMA's flood mapping program is.
Du and Rotunno (), using a long-term WRF daily simulation, verified such phenomena off the east coast of China due to the latitude differences. Q09 introduced uniform background wind into the R83 theory at the equator, resulting in the tilting of the gravity wave ray paths 1 due to Doppler shifting.
Physical oceanography is the study of physical conditions and physical processes within the ocean, especially the motions and physical properties of ocean waters.
Physical oceanography is one of several sub-domains into which oceanography is divided. Others include biological, chemical and geological oceanography. Physical oceanography may be subdivided into descriptive and dynamical. Offshore renewable energy includes several forms of energy extraction from oceans and seas, and the most common and successful offshore technologies developed so far are based on wind.
The results of this numerical study provide detailed accounts of the effects of stomatal encryption and crypt trichomes on the humidity profile, total leaf conductance, and transpiration.
Of course, crypts and trichomes will also affect overall conductances to CO 2, but the analysis of these effects involves further complexities (see below.

The Mid-Atlantic region of the Azores Archipelago is under the permanent influence of the Azores high pressure system, thereby providing sustained Ekman transport that facilitates the convergence in regional oceanography.
