Download On the relationship between water vapor over the oceans and sea surface temperature
Water vapor content of the atmosphere above the oceans can generally be prescribed from the sea surface temperature with a standard deviation of gcm The form of the relationship between precipitable water and sea surface temperature in the range Ts > 18°C also resembles.
Atmospheric water vapor has an important role in maintaining the hydrological cycle on the earth’s climate system. Water vapor integrated from the surface to the top of the atmosphere, often called column water vapor (CWV), is known to be related closely with sea surface temperature (SST) over the global ocean (e.g., Prabhakara et al.
; Raval and Ramanathan ; Stephens ; Cited by: An ideal and simple formulation is successfully derived that well represents a quasi-linear relationship found between the domain-averaged water vapor, Q (mm), and temperature, T (K), fields for the three tropical oceans (i.e., the Pacific, Atlantic and Indian Oceans) based on eleven GEOS-3 [Goddard Earth Observing System (EOS) Version-3] global re-analysis monthly by: 4.
Get this from a library. On the relationship between water vapor over the oceans and sea surface temperature. [Graeme L Stephens; United States. National Aeronautics and Space Administration.]. Increases in sea surface temperature have led to an increase in the amount of atmospheric water vapor over the oceans.
3 This water vapor feeds weather systems that produce precipitation, increasing the risk of heavy rain and snow (see the Heavy Precipitation and Tropical Cyclone Activity indicators). Sea surface temperature (SST) is a strong indicator of productivity, pollution, and global climate change, and this can be measured using thermal infrared (IR) bands from optical satellites.
Interpretive techniques are required to convert the data to actual temperature (Azmi, Agarwadkar, Bhattacharya, Apte, & Inamdar, ).An example SST map is shown in Fig. qy,s is described in appendix A. If water vapor density exponentially decreases with height, Hy provides the e-folding scale.
Figure 1 shows the scaled vertical struc-ture of moisture sorted as a function of Hy, where water vapor mixing ratio qy is normalized by its surface value qy, 1 illustrates that Hy well represents the con- trast between the BL and FT water vapor mixing ratios.
The relationship between water vapor path W and surface precipitation rate P over tropical oceanic regions is analyzed using 4 yr of gridded daily SSM/I satellite microwave radiometer data. A tight monthly mean relationship P (mm day21) 5 exp[(r 2 )] for.
Temperature is also important because of its influence on water chemistry. The rate of chemical reactions generally increases at higher temperature. Water, particularly groundwater, with higher temperatures can dissolve more minerals from the surrounding rock and will therefore have a higher electrical conductivity.
It is the opposite when. The most obvious relationship between sea surface temperature and water vapor is that both are driven by seasonal changes; both increase in the hemisphere experiencing summer.
Seasonal changes in water vapor, however, are more evident over land, and this results .
