Global Surface Air Temperature during Hurricane Frances (WMS) |
| Abstract |
As the Sun's energy reaches the Earth, it is either reflected, absorbed by the clouds, or absorbed by the Earth's surface. The part absorbed by the Earth's surface heats the Earth, which then heats the air just above the surface. This process occurs rapidly in the case of dry land and slowly in the case of the oceans. This animation shows the surface air temperature at an altitude of 2 meters for the whole globe from September 1, 2004, through September 5, 2004, during the period of Hurricane Frances in the western Atlantic Ocean and Typhoon Songda in the western Pacific Ocean. The animation clearly shows the air over land reacting rapidly to solar heating during the day and cooling at night, while the daily solar cyle is not visible in the temperature of the air over the ocean. A very dynamic region of changing air temperature is visible in the interaction between the cold air over Antarctica and the warmer mid-latitude air over the southern oceans during this region of polar night. Hurricane Frances and Typhhon Songda are just barely visible as circulating temperature patterns in the western Atlantic and Pacific Oceans. |

| Title |
Global High Altitude Wind Speed during Hurricane Frances (WMS) |
| Abstract |
The Earth's atmosphere exerts pressure based on the weight of the air above. Differences in pressure from place-to-place cause winds to try to flow from high pressure to low pressure regions to even out the differences, but the Earth's rotation and wind friction with the surface act to slow or divert the winds. This animation shows the high altitude wind speeds for the whole globe from September 1, 2004, through September 5, 2004, during the period of Hurricane Frances in the western Atlantic Ocean and Typhoon Songda in the western Pacific Ocean. At high altitudes, the difference between between high pressures from warm tropical air and low pressures from cold polar air try to force air from the tropics toward the poles, but the Earth's rotation diverts this flow to the east, resulting in the high velocity west-to-east jet stream flows at mid-latitudes. The circular flows from Frances and Songda can barely be seen at this altitude. |
