Urban heat waves Los Angeles vulnerable communities
2020/6/5
People living in low-income, disadvantaged communities across much of southern Los Angeles lack the means to cool their homes, posing a growing threat to their health -- and their lives -- from extrem...
Scientists Study Atmospheric Waves Radiating out of Hurricanes
Scientists Atmospheric Waves Radiating Hurricanes
2017/7/20
Researchers believe they have found a new way to monitor the intensity and location of hurricanes from hundreds of miles away by detecting atmospheric waves radiating from the centers of these powerfu...
Scientists link California droughts and floods to distinctive atmospheric waves
Scientists California droughts floods atmospheric waves
2017/4/27
The crippling wintertime droughts that struck California from 2013 to 2015, as well as this year's unusually wet California winter, appear to be associated with the same phenomenon: a distinctive wave...
On May 17, 2012 the National Weather Service’s Climate Prediction Center forecasted normal summer temperatures in the Northeast and Midwest United States and a 33 to 40 percent chance of abo...
The newtonian approach in the meteorological tide waves forecasting: preliminary observations in the East Ligurian harbours
meteorological tide waves Newtonian sea level compensation tide forecasting environmental harbours quality
2015/9/8
Sea level oscillations are the superposition of many contributions, among which the main are astronomic and meteorological low-frequency tides. In Ligurian Sea meteo-tide components, being most ample ...
Heating of the auroral ionosphere by traveling ionospheric disturbances initiated by atmospheric gravity waves
ionospheric dynamics plasma physics auroral phenomena
2015/8/28
In the presence of perturbations of the thermospheric auroral region produced by traveling ionospheric disturbances during the propagation of atmospheric gravity waves, an analytical expression of the...
Some recent papers proposed the use of the satellite images of Google Earth in teaching physics, in particular to see some behaviours of waves. Reflection, refraction, diffraction and interference are...
Experimental simulation of satellite observations of 100 kHz radio waves from relativistic electron beams above thunderclouds
satellite observations 100 kHz radio waves relativistic electron beams thunderclouds
2011/2/24
Relativistic electron beams above thunderclouds emit 100 kHz radio waves which illuminate the Earth's atmosphere and near-Earth space. This contribution aims to clarify the physical processes which ar...
Turbulence associated with mountain waves over Northern Scandinavia – a case study using the ESRAD VHF radar and the WRF mesoscale model
Turbulence mountain waves Northern Scandinavia the ESRAD VHF radar the WRF mesoscale model
2010/8/12
We use measurements by the 52 MHz wind-profiling radar ESRAD, situated near Kiruna in Arctic Sweden, and simulations using the Advanced Research and Weather Forecasting model, WRF, to study vertical w...
Can gravity waves significantly impact PSC occurrence in the Antarctic?

2009/12/3
A combination of POAM III aerosol extinction and CHAMP RO temperature measurements are used to examine the role of atmospheric gravity waves in the formation of Antarctic Polar Stratospheric Clouds (P...
Excitation of waves at 2 ωp,e and back propagating waves at ωp,e:a parametric study
waves at 2 ωp,e back propagating waves at ωp,e parametric study
2009/11/12
We present a parametric study of electrostatic waves generated with angular frequencies 2 wp,e and - wp,e by an electron beam using a one-dimensional Vlasov code. We consider a background plasma consi...
Properties of the average distribution of equatorial Kelvin waves investigated with the GROGRAT ray tracer

2009/11/9
Kelvin waves excited by tropospheric convection are considered to be one of the main drivers of the stratospheric quasi-biennial oscillation (QBO). In this paper we combine several measured data sets ...
Tropical cyclogenesis in a tropical wave critical layer: easterly waves
Tropical cyclogenesis tropical wave critical layer easterly waves
2009/8/7
The development of tropical depressions within tropical waves over the Atlantic and eastern Pacific is usually preceded by a "surface low along the wave" as if to suggest a hybrid wave-vortex structur...
