Communicating Winter Weather Surface Impacts

The University Corporation for Atmospheric Research, 2017

This lesson will introduce National Weather Service (NWS) forecasters to the benefits of pre-season coordination in understanding the critical needs of decision-makers, particularly the state and local Departments of Transportation (DOTs). The strategies used by DOTs to mitigate road impacts during the winter and how the NWS can best support their needs are also discussed. Learners will gain insight into the common methods of collaboration between the NWS and DOT, and the different types of winter weather events in which they work together. Learners will also practice communicating winter weat ...

Learners will gain insight into the common methods of collaboration between the NWS and DOT, and the different types of winter weather events in which they work together. Learners will also practice communicating winter weather forecast information that best support the concerns of DOT, including working through a simulation to see the effects of their communication choices on DOT decisions.

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, 2010

The 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 ...

Spring Cold Bias of SST and Minimal Wind Mixing in the Equatorial Pacific Cold Tongue

The 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, 2010

The 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 ...

Spatial Distributions of Atmospheric Radiative Fluxes and Heating Rates over China during Summer

The 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.

Seasonal Forecast Problems Refresher Training

The University Corporation for Atmospheric Research, 2002

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.
