Global Large-scale Precipita …
Title Global Large-scale Precipitation during Hurricane Frances (WMS)
Abstract Water vapor is a small but significant constituent of the atmosphere, warming the planet due to the greenhouse effect and condensing to form clouds. As moisture-laden air rises, the relative humidity increases until it saturates the air, at which time precipitation occurs. If the uplift of air is due to large-scale atmospheric motion, then the precipitation is called large-scale, or dynamic. This animation shows the large-scale precipitation 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. Large-scale precipitation tends to be continuous and to come from decks of stratus clouds rather than from thunderstorms.

Title Global Cloud Cover during Hurricane Frances (WMS)
Abstract Water vapor is a small but significant constituent of the atmosphere, warming the planet due to the greenhouse effect and condensing to form clouds which both warm and cool the Earth in different circumstances. Warm, moisture-laden air moving out from the tropics brings clouds and rainfall to the temperate zones. This animation shows the cloud cover 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 cloud cover in any region significantly affects the energy balance since sunlight reflected from the clouds is not available to heat the surface. The motion of clouds in this animation clearly indicates the speed and direction of winds around the globe.

Title Global Convective Precipitation during Hurricane Frances (WMS)
Abstract Water vapor is a small but significant constituent of the atmosphere, warming the planet due to the greenhouse effect and condensing to form clouds. As moisture-laden air rises, the relative humidity increases until it saturates the air, at which time precipitation occurs. If the uplift of air is due to strong updrafts and unstable air systems, as in thunderstorms, then the precipitation is called convective. This animation shows the convective precipitation 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. Convective precipitation is more intense but less long-lasting than large-scale precipitation.

Title Hurricane Katrina Sea Surface Temperature (WMS)
Abstract This visualization shows the cold water trail left by Hurricane Katrina. The data is from August 23 through 30, 2005. The colors on the ocean represent the sea surface temperatures, and satellite images of the hurricane clouds are laid over the temperatures to clearly show the hurricane positions. Orange and red depict regions that are 82 degrees F and higher, where the ocean is warm enough for hurricanes to form. Hurricane winds are sustained by the heat energy of the ocean, so the ocean is cooled as the hurricane passes and the energy is extracted to power the winds. The sea surface temperatures are 3-day moving averages based on the AMSR-E instrument on the Aqua satellite, while the cloud images were taken by the Imager on the GOES-12 satellite.

Title GOES-12 Imagery of Hurricane Katrina: Visible Close-up (WMS)
Abstract The GOES-12 satellite sits at 75 degrees west longitude at an altitude of 36,000 kilometers over the equator, in geosynchronous orbit. At this position its Imager instrument takes pictures of cloud patterns in several wavelengths for all of North and South America, a primary measurement used in weather forecasting. The Imager takes a pattern of pictures of parts of the Earth in several wavelengths all day, measurements that are vital in weather forecasting. This animation shows a daily sequence of GOES-12 images in the visible wavelengths, from 0.52 to 0.72 microns, during the period that Hurricane Katrina passed through the Gulf of Mexico. At one kilometer resolution, the visible band measurement is the highest resolution data from the Imager, which accounts for the very high level of detail in these images. For this animation, the cloud data was extracted from GOES image and laid over a background color image of the southeast United States.

Abstract The temperature of the surface of the world's oceans provides a clear indication of the state of the Earth's climate and weather. In this visualization sequence covering the period from January to June, 2005, the most obvious effects are the north-south movement of warm regions across the equator due to the seasonal movement of the sun and the seasonal advance and retreat of the sea ice near the North and South poles. It is also possible to see the Gulf Stream, the warm river of water that parallels the east coast of the United States before heading towards northern Europe, in this data.

Title Global Atmospheric Surface Pressure during Hurricane Frances (WMS)
Abstract The weight of the Earth's atmosphere exerts pressure on the surface of the Earth. This pressure varies from place-to-place due the variations in the Earth's surface since higher altitudes have less atmosphere above them than lower altitudes. Atmospheric pressure also varies from time-to-time due to the uneven heating of the atmosphere by the sun and the rotation of the Earth, causing weather. This animation shows the atmospheric surface pressure 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 major changes in pressure occur over land where the surface altitude varies, but the sharp, moving low pressures areas for Frances and Songda can be clearly seen in the oceans. Since changing surface pressure areas over land are hard to see in these images due to the strong altitude variations, plots of the atmospheric surface pressure are almost never used to study the weather. A different plot, of sea-level pressure, is used instead.

Title 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.

Title Global Surface Latent Heat Flux 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 surface heats the Earth, which causes surface water to evaporate to the air, particularly over oceans or moist land. Similarly, a cold surface causes water to condense from the air onto the land or ocean. Latent heat flux is the amount of energy moving from the surface to the air due to evapolation (positive values) or from the air to the land due to condensation (negative values). This animation shows the latent heat flux 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 evaporation over land only during the heat of the day, while the evaporation over the ocean is continuous throughout the day. The highest positive latent heat flux occurs during hurricanes and typhoons, as these events are powered by the movement of heat energy from the warm ocean to the atmosphere, seen here in Hurricane Frances and Typhoon Songda. Significant negative latent heat flux is somewhat rare and occurs over the ocean only during certain configurations of air and surface conditions.

As it moved through the Caribbean, Emily intensified into a powerful Category 4 storm with winds over 250 kilometers per hour (150 mph) and gusts as high as 300 kilometers per hour (184 mph), making it the most powerful storm to form before August. The previous record was set by Hurricane Dennis, which ripped through the Caribbean during the first week of July 2005. Emily's Category 4 status also made 2005 the only year to produce two Category 4 storms before the end of July.

Abstract The weight of the Earth's atmosphere exerts pressure on the surface of the Earth. This pressure varies from place-to-place due the variations in the Earth's surface since higher altitudes have less atmosphere above them than lower altitudes. Atmospheric pressure also varies from time-to-time due to the uneven heating of the atmosphere by the sun and the rotation of the Earth, causing weather. In order to see the changes in pressure which affect the weather, the variation due to altitude is removed from the surface pressure, creating a quantity called sea level pressure. This animation shows the atmospheric sea level pressure 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 sharp, moving low pressures areas for Frances and Songda can be clearly seen in the oceans. Even with the direct effect of altitude removed, cold high-altitude regions such as the South Pole and the Himalayan Plateau still exhibit lower-than-normal pressures, probably due to the interaction of cold air over those regions with the warmer air in the surrounding regions.

Title Global 300 hPa Geopotential Height during Hurricane Frances (WMS)
Abstract The Earth's atmosphere exerts pressure based on the weight of the air above, so the pressure reduces with rising altitude. This rate of pressure reduction with altitude is based on the temperature of the air, with the pressure of colder air reducing faster with altitude than warmer air. Therefore, a surface of constant pressure has a lower altitude at the poles than the equator. This animation shows the altitude above sea level (the geopotential height) of the 300 hectopascal (hPa) pressure surface 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. This pressure is about one-third of the normal pressure at sea level. The largest downward slope of this surface occurs in the mid-latitudes and is shown in yellow in the animation. At this region, air is trying to flow from the equator towards the poles to reduce the slope, but the rotation of the Earth forces the flow to divert to the east, forming the strong west-to-east jet stream flows in these regions. Frances and Songda can be seen as sharp yellow dots of reduced height in their respective locations.

Title Global Surface Wind Speed during Hurricane Frances (WMS)
Abstract The weight of the Earth's atmosphere exerts pressure on the surface of the Earth. This pressure varies from place-to-place and from time-to-time due to surface irregularities, uneven heating of the atmosphere by the sun, and the Earth's rotation. 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 surface 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. The highest, smoothest winds occur over the oceans where there are no surface irregularities to break up the flow, while flows over land tend to be irregular and highly variable. The highest winds occur in Hurricane Frances and Typhoon Songda, but note that the hurricane's wind speeds reduce dramatically when crossing Florida.

GOES-10 Imagery of Hurricane …
Title GOES-10 Imagery of Hurricane Katrina: Full Disk Longwave Infrared (WMS)
Abstract The GOES-10 satellite sits at 135 degrees west longitude at an altitude of 36,000 kilometers over the equator, in geosynchronous orbit. At this position its Imager instrument takes pictures of cloud patterns in several wavelengths for the Pacific Ocean, a primary measurement used in weather forecasting. Every three hours the Imager takes a picture of the full disk of the Earth. This animation shows a sequence of these full disk images in the longwave infrared wavelengths, from 10.2 to 11.2 microns, during the period that Hurricane Katrina passed through the Gulf of Mexico. This wavelength band is the most common one for observing cloud motions and severe storms throughout the day and night.
