Bitemporal hemianopsia (or Bitemporal hemianopia) is the medical description of a type of partial blindness where vision is missing in the outer half of both the right and left visual field.
Global winds. Earthâs orbit around the sun and its rotation on a tilted axis causes some parts of Earth to receive more solar radiation than others. This uneven heating produces global circulation patterns.offsite link For example, the abundance of energy reaching the equator produces hot humid air that rises high into the atmosphere.
1 1. Global and Local Winds. 2  2. Air Movementâ¢Wind is the movement of air caused by differences in air pressureâ¢The greater the difference, the faster the wind moves.3  3. Air Pressureâ¢Differences in air pressure are caused by the uneven heating of Earthâ¢Uneven heating produces pressure belts which occur every 30Â° latitude. Global Windsâ¢The combination of pressure belts and the Coriolis Effect cause global windsâ¢These are polar easterlies, westerlies, and trade winds. 2  7. 3  Polar Easterliesâ¢Wind belts that extend from the poles to 60Â° latitudeâ¢Formed from cold sinking air moving from the poles creating cold temperatures. 4  8.
