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.
From year to year, winds and air pressure patterns change, causing different forces to act on the solid Earth. During El NiÃ±o years, for example, the rotation of the Earth may slow ever so slightly because of stronger winds, increasing the length of a day by a fraction of a millisecond (thousandth of a second).
