What do we call a rapid change in temperature with depth?
pycnocline. A layer of rapid change of ocean temperature with depth is called a. thermocline.
What refers to the change in temperature with depth in the ocean?
Below the mixed layer there is a rapid decline in temperature over a fairly narrow increase in depth. This is called the thermocline . Below the thermocline the deep ocean temperature is fairly constant at about 2o C, continuing down to the bottom.
What is a rapid change in ocean density with change in depth?
A layer in the ocean where a rapid change in ocean density occurs with a change in depth is called a: halocline.
What do you call a rapid change in density with depth?
The pycnocline encompasses both the halocline (salinity gradients) and the thermocline (temperature gradients)refers to the rapid change in density with depth. Because density is a function of temperature and salinity, the pycnocline is a function of the thermocline and halocline. 2.
What do you call a rapid change in salinity with depth?
halocline, vertical zone in the oceanic water column in which salinity changes rapidly with depth, located below the well-mixed, uniformly saline surface water layer.
What do El Nino mean?
El Niño means Little Boy, or Christ Child in Spanish. South American fishermen first noticed periods of unusually warm water in the Pacific Ocean in the 1600s. The full name they used was El Niño de Navidad, because El Niño typically peaks around December. El Niño can affect our weather significantly.
Where is the thermocline in the ocean?
thermocline, oceanic water layer in which water temperature decreases rapidly with increasing depth. A widespread permanent thermocline exists beneath the relatively warm, well-mixed surface layer, from depths of about 200 m (660 feet) to about 1,000 m (3,000 feet), in which interval temperatures diminish steadily.
What is a thermocline in the ocean?
A thermocline is the transition layer between the warmer mixed water at the surface and the cooler deep water below. It is relatively easy to tell when you have reached the thermocline in a body of water because there is a sudden change in temperature.
What is an area of rapid change in density?
The pycnocline encompasses both the halocline (salinity gradients) and the thermocline (temperature gradients)refers to the rapid change in density with depth. Because density is a function of temperature and salinity, the pycnocline is a function of the thermocline and halocline. 2.
What is a halocline in the ocean?
halocline, vertical zone in the oceanic water column in which salinity changes rapidly with depth, located below the well-mixed, uniformly saline surface water layer.
What are ocean Clines?
What are Clines? Clines are layers within water that have different properties than the surrounding water. They may vary in temperature, salinity, density, or chemistry. Clines are usually horizontal and are often vertically thin in comparison to the body of water around them.
What is El Niño vs La Niña?
El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.
What is the difference between El Niño and La Nino?
El Niño events are associated with a warming of the central and eastern tropical Pacific, while La Niña events are the reverse, with a sustained cooling of these same areas. These changes in the Pacific Ocean and its overlying atmosphere occur in a cycle known as the El Niño–Southern Oscillation (ENSO).
What is meant by thermocline?
A thermocline is the transition layer between the warmer mixed water at the surface and the cooler deep water below. It is relatively easy to tell when you have reached the thermocline in a body of water because there is a sudden change in temperature.
What is the difference between thermocline and halocline?
A halocline is most commonly confused with a thermocline – a thermocline is an area within a body of water that marks a drastic change in temperature. A halocline can coincide with a thermocline and form a pycnocline. Haloclines are common in water-filled limestone caves near the ocean.
What is thermocline and halocline?
A halocline is most commonly confused with a thermocline – a thermocline is an area within a body of water that marks a drastic change in temperature. A halocline can coincide with a thermocline and form a pycnocline. Haloclines are common in water-filled limestone caves near the ocean.
How do thermocline and halocline relate?
The pycnocline encompasses both the halocline (salinity gradients) and the thermocline (temperature gradients)refers to the rapid change in density with depth. Because density is a function of temperature and salinity, the pycnocline is a function of the thermocline and halocline. 2.
What is El Niño and La Niña and what are the characteristics of each?
El Niño is characterized by a positive ONI greater than or equal to +0.5°C. La Niña is characterized by a negative ONI less than or equal to -0.5°C. Whenever the ONI is between +0.5 and -0.5, conditions are referred to as ENSO-neutral.
Is El Niño wet or dry?
El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North. El Niño also has a strong effect on marine life off the Pacific coast.
What does nino mean?
boy; child noun, plural ni·ños (nee-nyaws; English neen-yohz). Spanish. boy; child.
What is the meaning of Hypolimnion?
Definition of hypolimnion : the part of a lake below the thermocline made up of water that is stagnant and of essentially uniform temperature except during the period of overturn.
What is meant by thermocline halocline and pycnocline?
The pycnocline encompasses both the halocline (salinity gradients) and the thermocline (temperature gradients)refers to the rapid change in density with depth. Because density is a function of temperature and salinity, the pycnocline is a function of the thermocline and halocline.
What is a Hydrocline?
In oceanography, a halocline (from Greek hals, halos 'salt' and klinein 'to slope') is a cline, a subtype of chemocline caused by a strong, vertical salinity gradient within a body of water.
What is halocline and thermocline?
The pycnocline encompasses both the halocline (salinity gradients) and the thermocline (temperature gradients)refers to the rapid change in density with depth. Because density is a function of temperature and salinity, the pycnocline is a function of the thermocline and halocline.
Why is El Niño called El Niño?
Fishermen off the west coast of South America were the first to notice appearances of unusually warm water that occurred at year's end. The phenomenon became known as El Niño because of its tendency to occur around Christmas time. El Niño is Spanish for "the boy child" and is named after the baby Jesus.
What is the difference El Niño and La Niña?
El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.
What causes La Niña and El Niño?
El Niño and La Niña result from interaction between the surface of the ocean and the atmosphere in the tropical Pacific. Changes in the ocean impact the atmosphere and climate patterns around the globe. In turn, changes in the atmosphere impact the ocean temperatures and currents.
What does Nina and Nino mean?
El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.
What does Niña mean?
noun, plural ni·ñas (nee-nyahs). Spanish. girl; child.
What do you mean by thermocline?
