Spring Cold Bias of SST and Minimal Wind Mixing in the Equatorial Pacific Cold Tongue
Atmospheric and Oceanic Science Letters, Volume 3 Number 6. Lin Peng-Fei; Liu Hai-Long; Li Chao; et al. - Science Press, 2010The authors investigate the relationship between bias in simulated sea surface temperature (SST) in the equatorial eastern Pacific cold tongue during the boreal spring as simulated by an oceanic general circulation model (OGCM) and minimal wind mixing (MWM) at the surface. The cold bias of simulated SST is greatest during the boreal spring, at approximately 3°C. A sensitivity experiment reducing MWM by one order of magnitude greatly alleviates cold biases, especially in March-April. The decrease in bias is primarily due to weakened vertical mixing, which preserves heat in the uppermost layer a ...

in Atmospheric and Oceanic Science Letters > Volume 3 Number 6 (16 November 2010) . - p.342-346The authors investigate the relationship between bias in simulated sea surface temperature (SST) in the equatorial eastern Pacific cold tongue during the boreal spring as simulated by an oceanic general circulation model (OGCM) and minimal wind mixing (MWM) at the surface. The cold bias of simulated SST is greatest during the boreal spring, at approximately 3°C. A sensitivity experiment reducing MWM by one order of magnitude greatly alleviates cold biases, especially in March-April. The decrease in bias is primarily due to weakened vertical mixing, which preserves heat in the uppermost layer and results in warmer simulated SST. The reduction in vertical mixing also leads to a weak westward current in the upper layer, which further contributes to warmer SST estimates. These findings imply that there are large uncertainties about simple model parameters such as MWM at the oceanic surface.

Spatial Distributions of Atmospheric Radiative Fluxes and Heating Rates over China during Summer
Atmospheric and Oceanic Science Letters, Volume 3 Number 5. Yang Da-Sheng; Wang Pu-Cai - Science Press, 2010The latitude-altitude distributions of radiative fluxes and heating rates are investigated by utilizing CloudSat satellite data over China during summer. The Tibetan Plateau causes the downward shortwave fluxes of the lower atmosphere over central China to be smaller than the fluxes over southern and northern China by generating more clouds. The existence of a larger quantity of clouds over central China reflects a greater amount of solar radiation back into space. The vertical gradients of upward shortwave radiative fluxes in the atmosphere below 8 km are greater than those above 8 km. The la ...

in Atmospheric and Oceanic Science Letters > Volume 3 Number 5 (16 September 2010) . - p.248-251The latitude-altitude distributions of radiative fluxes and heating rates are investigated by utilizing CloudSat satellite data over China during summer. The Tibetan Plateau causes the downward shortwave fluxes of the lower atmosphere over central China to be smaller than the fluxes over southern and northern China by generating more clouds. The existence of a larger quantity of clouds over central China reflects a greater amount of solar radiation back into space. The vertical gradients of upward shortwave radiative fluxes in the atmosphere below 8 km are greater than those above 8 km. The latitudinal-altitude distributions of downward longwave radiative fluxes show a slantwise decreasing trend from low latitudes to high latitudes that gradually weaken in the downward direction. The upward longwave radiative fluxes also weaken in the upward direction but with larger gradients. The maximum heating rates by solar radiation and cooling rates by longwave infrared radiation are located over 28-40°N at 7-8 km mean sea level (MSL), and they are larger than the rates in the northern and southern regions. The heating and cooling rates match well both vertically and geographically.

Space Weather Basics, 2nd Edition
This lesson presents an overview of space weather processes, their impacts on Earth and human activities, and the technologies used for forecasting space weather events. The lesson goal is to provide NWS forecasters a basic understanding of space weather and the operations of NOAA's Space Weather Prediction Center (SWPC). It will be of interest to a general audience as well.

Global change and the Earth System: executive summary
This executive summary describes a book that sets out what is known about global change and the nature of the Earth System. It addresses a number of important but difficult questions. How does the Earth System operate in the absence of significant human influence? How can human-driven effects be discerned from those due to natural variability? What are the implications of global change for human well-being? How robust is the Earth System in the face of this new internal force of change? Can human activities trigger abrupt and potentially irreversible changes to which adaptation would ...

Physics of the Aurora: Earth Systems
This interactive learning module introduces the systems and processes through which the Earth's magnetic field and upper atmosphere are influenced by the sun, eventually leading to the magnificent auroral displays. Developed especially for university professors and students in the fields of physics and astronomy, this module includes sections on the history, lore, and science of the aurora, the magnetosphere, the thermosphere-ionosphere, basic electromagnetism, and upper-atmospheric physics.

Seasonal Forecast Problems Refresher Training
This prototype module was originally intended as a review of seasonal weather regimes and hazards for regions that are of particular interest to the Air Force Weather Agency. Although the project was discontinued, the section on summer weather in the southeast U.S. is available as an forecaster's training aid and as an example of this type of training.

Operational hydrology report (OHR), 26. Methods of measurement and estimation of discharges at hydraulic structures
A review of methods for the measurement and estimation of discharges at hydraulic structures and pressure conduits with the aim of using such facilities, where they already exist, as an alternative to the construction of discharge measurement stations. Focus is on methods of flow estimation at structures commonly installed in reservoirs, dams and canals as well as standard methods for the measurement of open-channel and pipe flow. Mention is also made of the use of pumping stations and navigation locks.
