| This is particularly true when propagation depends on reflection from the ionosphere as it does for shortwaves. |
|
| This layer also serves as a good reflector of shortwaves during the day and into the night, until its reflectivity drops. |
|
| Obviously, one major effect of radiation is, especially for the shortwaves, to warm the Earth surface. |
|
| Radio Shack is out of everything: generators, shortwaves, water-filtration units, Tasers, Kevorkians, D batteries.... Dude says try the Sharper Image, and then just starts laughing. |
|
| Both Rossby waves and shortwaves embedded within the flow around Rossby waves migrate equatorward of the polar cyclones located in both the Northern and Southern hemispheres. |
