The east–west migration of the tropical upper-tropospheric trough (TUTT) on the interannual time scale and its influence on tropical cyclone (TC) formation over the western North Pacific (WNP) is ...

Spiral troughs found on the surface of Mars are in situ ice-excavated canyons with a total volume 10 times that of the Grand Canyon, making them one of the largest and youngest geologic ...

The spiral troughs of Mars' polar ice caps have been called the most enigmatic landforms in the solar system. The deep canyons spiraling out from Red Planet's North and South poles cover ...

Heavy rains accompanied with gusty winds lashed the state on Wednesday evening. The reason for this was an offshore trough formation in the Arabian Sea, on Tuesday evening. “We wanted to lift the ...

Ice wedges are common features of the subsurface in permafrost regions. They develop by repeated frost cracking and ice vein growth over hundreds to thousands of years. Ice-wedge formation causes the ...

View of a Mars polar trough, approximately 20 kilometers across and a few hundred meters deep. The image shows a mound (orange dot) and a depression (blue dot) that are concentrically layered. Some of ...
