A large-scale, stagnant weather pattern — known as an Omega blocking event — slowed the Rossby wave over Russia and prevented the normal progression of weather systems from west to east.As a result, a large region of high-pressure formed over Russia trapping a hot, dry air mass over the area. As the high lingered, the land surface dried and the normal transfer of moisture from the soil to the atmosphere slowed. Precipitation ceased, vegetation dried out, and the region became a taiga tinderbox.Meanwhile, the blocking pattern created unusual downstream wind patterns over Pakistan. Areas of low pressure on the leading edge of the Rossby wave formed in response to the high, pulling cold, dry Siberian air into lower latitudes.This cold air from Siberia clashed with warm, moist air arriving over Pakistan from the Bay of Bengal as part of the monsoon. There's nothing unusual about moisture moving north over India toward the Himalayas. It's a normal part of the monsoon. However, in this case, the unusual wind patterns associated with the blocking high brought upper level air disturbances farther south than typical, which in effect helped shifted the entire monsoon system north and west.This brought heavy monsoon rains — centered over parts of India — squarely over the northern part of Pakistan, a region ill-prepared to handle large amounts of rain. || ", "hits": 30 }, { "id": 10737, "url": "https://svs.gsfc.nasa.gov/10737/", "result_type": "Produced Video", "release_date": "2011-08-05T00:00:00-04:00", "title": "Tohoku Tsunami Creates Antarctic Icebergs", "description": "Nearly 50 square miles of ice broke off the Sulzberger Ice Shelf on the coast of Antarctica, resulting from waves generated by the Tohoku earthquake and tsunami that struck Japan in March 2011. || ", "hits": 30 }, { "id": 3804, "url": "https://svs.gsfc.nasa.gov/3804/", "result_type": "Visualization", "release_date": "2010-12-12T00:00:00-05:00", "title": "Human Consumption of Global Plant Production, 2005", "description": "On Dec. 14, 2010 NASA Goddard researchers conducted a press briefing at the American Geophysical Union Fall 2010 meeting, entitled, \"Satellite Supported Estimates of Human Rate of NPP carbon Use on Land: Challenges Ahead.\" In the first measurement of this trend, the research showed humans are using an increasing amount of Earth's annual production of photosynthetic land plants due to both increases in population and per capita consumption, and that amount of Net Primary Production (NPP) required rose from 20 to 25 percent from 1995 to 2005.This visualization illustrates the relationship between human acquistition of net primary productivity (HANPP) and NPP itself, by presenting the ratio of HANPP to NPP. It is a carbon balance sheet showing the percent of terrestrial net primary production that is required to provide food, fiber, and wood-based fuels for the world's global population in 2005.Measured in terms of carbon, regions where the populations are consuming more than is generated on the landscape show up as yellows and reds. The colors are presented on a logarithmic scale, meaning that the value of the data at each unit on the scale is ten times that of the previous unit; i.e. areas in red are 100 times (or greater) the value of areas in green. Therefore yellow, for example, with a value of HANPP/NPP = 10^0, or 1, represents regions were people require an amount of NPP that is 100 percent of the regional production, and red represents regions where people require more production than is locally available, up to 1000 percent and beyond. Values of less than 10 percent are not shown. This map shows where populations are highly dependent upon a food and fiber distribution system and are arguably potentially vulnerable to climate change. || ", "hits": 8 }, { "id": 10633, "url": "https://svs.gsfc.nasa.gov/10633/", "result_type": "Produced Video", "release_date": "2010-08-24T07:00:00-04:00", "title": "Katrina Retrospective: 5 Years After the Storm", "description": "On August 29, 2005, Hurricane Katrina made landfall along the Gulf Coast.

As more ice moves from glaciers on land into the ocean, it raises sea levels. Jakobshavn Isbrae is Greenland's largest outlet glacier, draining 6.5 percent of Greenland's ice sheet area. The ice stream's speed-up and near-doubling of ice flow from land into the ocean has increased the rate of sea level rise by about .06 millimeters (about .002 inches) per year, or roughly 4 percent of the 20th century rate of sea level increase.

The first automated technique for determining SST was accomplished by measuring the temperature of water in the intake port of large ships. A large network of coastal buoys in U.S. waters is maintained by the National Data Buoy Center (NDBC). Since about 1990, there has also been an extensive array of moored buoys maintained across the equatorial Pacific Ocean designed to help monitor and predict the El Niño phenomenon. Since the 1980s satellites have been increasingly utilized to measure SST and have provided an enormous leap in our ability to view the spatial and temporal variation in SST. The satellite measured SST provides both a synoptic view of the ocean and a high frequency of repeat views, allowing the examination of basin-wide upper ocean dynamics not possible with ships or buoys. For example, a ship traveling at 10 knots (20 km/h) would require 10 years to cover the same area a satellite covers in two minutes.This animation uses SST data taken at nighttime from the MODIS/Aqua and MODIS/Terra satellites. This data has many important applications that permit scientists to use ocean temperatures to observe ocean circulation and locate major ocean currents. Ocean current analysis can facilitate ocean transportation. Additionally, by using SST, scientists can monitor changes in ocean temperatures and relate these to weather and climate changes like coral bleaching around the Great Barrier Reef.

From season to season, snow coverage and depth affect soil moisture and water availability, which directly influence agriculture, wildfire occurrences, and drought. In the long term, the part of the Earth's surface covered by snow reflects up to 80 or 90 percent of the incoming solar radiation as opposed to the 10 or 20 percent that uncovered land reflects, and this has important consequences for the Earth's climate. Satellites identify the snow cover precisely by looking at the difference between light reflected off snow in the visible and the infrared wavelengths. This visualization shows the snow cover over North America from October, 2001, through April, 2002, as measured by the MODIS instrument on the Terra satellite. Since this instrument cannot measure snow cover through clouds, this visualization designates an area as covered by snow when the instrument takes a valid measurement showing greater than 50% snow coverage in that area. This area is assumed to be covered in snow until the instrument takes a valid measurement showing less than 40% coverage in that same area.
