      The Northeast Pacific hurricane season was highly active, with above-average intensity and frequency events, and a rare landfalling Hawaiian hurricane. We show that the anomalous northern extent of sea surface temperatures and anomalous vertical extent of upper ocean heat content above 26 °C throughout the Northeast and Central Pacific Ocean may have influenced three long-lived tropical.

        Zonal heat advection (ZHA) plays an important role in the variability of the thermal structure in the tropical Pacific Ocean, especially in the western Pacific warm pool (WPWP). Using the Simple Ocean Data Assimilation (SODA) Version /4 for the period –, this paper presents a detailed analysis of the climatological and seasonal ZHA in the tropical Pacific Ocean. A subset of the global ocean temperature climatology is used to characterize the observed seasonal variability in the near-surface thermal structure of the tropical Indian Ocean. In the near-surface isothermal layer the seasonal variability is least in the warm pool region and increases poleward. Over much of the tropical Indian Ocean, local surface heat fluxes overwhelm horizontal advection.

        The relationship between upper-ocean thermal structure and typhoon intensity has been discussed in many studies for a summer season (Emanuel et al , Emanuel , Webster et al , Lin et al , , Wu et al ), so we first examine changes in the upper ocean in May only.

N2 - The salient feature of the oceanic thermal structure is a remarkably shallow thermocline, especially in the Tropics and subtropics. What factors determine Cited by: thermal structure of the ocean: cold water upwells be-cause the thermocline is sufficiently shallow to allow the entrainment of cold water into the mixed layer.

Re-gions of upwelling are therefore special in that the ver-tical thermal structure is directly related to the heat bud-get. This is particularly evident during El Nin˜o events. The organic matter produced in the eastern and central tropical Pacific that escapes upper ocean remineralization is exported to the deep ocean.

Conversely, in the warm pool thermal stratification restricts subsurface nutrients from entering the euphotic zone, resulting in low surface nutrients, primary productivity and carbon export.

Abstract While El Niño–Southern Oscillation (ENSO) influences eastern North Pacific (ENP) tropical cyclones (TCs) through a variety of atmospheric processes when examined concurrently, ocean. These strong zonal currents are important for mass, heat, and tracer distributions of the Indo-Pacific Ocean.

Especially their heat transport plays an essential role in setting up the basic thermal structure of the tropical Pacific Ocean, such as the west Pacific warm pool and the east Pacific cold tongue (Enfield ; Clement et al.

Eastern Pacific Tropical Cyclones intensified by El Niño delivery of subsurface ocean heat and other upper-ocean thermal structure (UOTS) features on TC intensity have been qualitatively.

For the tropical Pacific and Atlantic oceans, internal modes of variability that lead to climatic oscillations have been recognized1,2, but in the Indian Ocean region a similar ocean–atmosphere.

The tropical Pacific has a conspicuous discrepancy, in which, the sea level is rising in the western Pacific but falling in the eastern Pacific in the satellite altimetry era (Cazenave et al., ). The tropical Pacific plays a crucial role in affecting the processes in the extra-tropical basins.

A nonlocal effect associated with eastern Atlantic Ocean temperature provides additional predictive skill of tropical cyclone activity when compared with the well-known local modulation effect associated with sea surface temperature.

The most active tropical cyclone seasons occur for lower than normal wind shear conditions and less intense trade winds, which are associated with higher eastern.

Upper Ocean Structure: Wind and Buoyancy-forced Upper Ocean the ocean has thermal and mechanical inertia relative to the atmosphere. The ocean thus forcing.

In the second example, the seasonal cycle of the eastern tropical Pacific, the atmosphere and ocean are coupled, so that wind and buoyancy forcing lead to a sequence of events. A Pacific hurricane is a mature tropical cyclone that develops within the northeastern and central Pacific Ocean to the east of °W, north of the equator.

For tropical cyclone warning purposes, the northern Pacific is divided into three regions: the eastern (North America to °W), central (°W to °), and western (° to °E), while the southern Pacific is divided into 2. Meridional sections of upper ocean zonal currents, potential temperature, and salinity are estimated at ten longitudes from °E to 95°W using Conductivity–Temperature–Depth and Acoustic Doppler Current Profiler data from synoptic sections taken in the tropical Pacific between °E and 86°W, mostly in the s.

The Indonesian Throughflow (ITF) is an important component of the upper cell of the global overturning circulation that provides a low-latitude pathway for warm, fresh waters from the Pacific to enter the Indian Ocean.

Variability and changes of the ITF have significant impacts on Indo-Pacific oceanography and global climate. In this paper, the observed features of the ITF and its interannual. On the other hand SST drives the interannual variations in the upper-ocean thermal field and hurricane activity mainly in the northern part of the basin.
