Iran, Turkey, Armenia – January 27th, 2013

This cloud-covered image highlights the use of the Chelys Satellite Rapid Response System (SRRS) “borders” feature, which overlays countries’ boundaries on satellite images. Here, Iran, Turkey, Georgia, Russia and Azerbaijan can be observed counterclockwise from the bottom right, with Armenia in the center. While Lake Van, in Turkey, is partially visible through the clouds, the borders feature shows the location of other lakes that would be hidden: Lake Urmia (bottom), in Iran, Lake Sevan (center), in Armenia, and the Mingachevir Reservoir (upper right), in Azerbaijan.

Iraq – January 27th, 2013

Although a large portion of the Middle East is cloud covered, the use of the Chelys Satellite Rapid Response System (SRRS) “borders” feature allows the borders between Iraq (center), Iran (right) and Kuwait (bottom left) to be clearly visible. This features also allows three lakes’ locations in Iraq to be observed despite the clouds: Lake Tharthar, Lake Habbaniyah and Lake Milh (top to bottom).

Area of Convection Over Gulf of Carpentaria, Australia

Australia – January 26th, 2013

An area of convection hangs over the Gulf of Carpentaria, between the Northern Territory and Queensland, Australia. Warning centers have not reported any concern over the system developing into a tropical storm. Although the convection covers the gulf, its shoreline can be seen thanks to the use of the Chelys Satellite Rapid Response System (SRRS) “borders” feature (best observed in full image).

New Borders Feature in Action – January 27th, 2013 – EOSnap Celebrates its 6000th Post!

Egypt, without borders

EOSnap celebrates our 6000th post by focusing on the new “borders” feature of the Chelys Satellite Rapid Response System (SRRS). The feature allows users to download satellite images that show not only a true, traditional view of the terrain below, but also the borders of countries. The feature is particularly useful for seeing the outline of land despite cloudcover. It can also be used to show the location of lakes.

In the main image, the border between Egypt and Sudan is clearly visible as a horizontal line. The contours of Lake Nasser, which would otherwise be invisible except for its southern tip due to heavy cloud cover (see thumbnail image “Egypt, without borders” for a look at the original, borderless image), are easily distinguishable, highlighted in blue. The thumbnail image of Mozambique shows the country’s shoreline despite an area of convection, in this case a potential area of cyclone formation, looming over the coast. The thumbnail image of Bolivia and Peru focuses on Lake Titicaca, and clearly shows where the lake is divided between the two countries. The thumbnail image of southern USA, in addition to sediments from the Mississippi River, shows the border between Louisiana (right) and Texas (left), as well as the Toledo Bend Reservoir, despite the thick clouds covering the upper half of the image.

Track of TS 27W

Tropical Storm Wukong (27W) located approximately 285 nm south-southwest of Manila, Philippines, has tracked west-southwestward at 14 knots over the past six hours. Here, the system can be seen encroaching on the Philippines, whose borders are visible despite the convection covering them due to the use of the Chelys Satellite Rapid Response System (SRRS) “borders” feature.

Animated enhanced infrared satellite imagery shows the low level circulation center has become fully exposed and ragged as the main convection was sheared almost 200 nm to the north. The same animation shows the convective tops have significantly warmed as the bands unraveled and dispersed. Maximum significant wave height is 11 feet.

Upper level analysis indicates the system is 05 degrees south of the ridge axis in an area of moderate to strong (20-30 knot) southerly vertical wind shear (VWS). The cyclone is tracking along the southern extension of a deep-layered subtropical ridge to the north. The system is expected to dissipate in 12 hours due to the high VWS, exacerbated by a cold northeasterly surface wind surge in the South China Sea.
