Hail is a form of solid precipitation. It is distinct from ice pellets, though the two are often confused. It consists of balls or irregular lumps of ice, each of which is called a hailstone. Ice pellets generally fall in cold weather, while hail growth is greatly inhibited during low surface temperatures.
Tláloc is the god of rain in Aztec religion. He was also a deity of earthly fertility and water, worshipped as a giver of life and sustenance. This came to be due to many rituals, and sacrifices that were held in his name. He was feared, but not maliciously, for his power over hail, thunder, lightning, and even rain. He is also associated with caves, springs, and mountains, most specifically the sacred mountain where he was believed to reside. Cerro Tláloc is very important in understanding how rituals surrounding this deity played out. His followers were one of the oldest and most universal in ancient Mexico.
A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder. Relatively weak thunderstorms are sometimes called thundershowers. Thunderstorms occur in a type of cloud known as a cumulonimbus. They are usually accompanied by strong winds and often produce heavy rain and sometimes snow, sleet, or hail, but some thunderstorms produce little precipitation or no precipitation at all. Thunderstorms may line up in a series or become a rainband, known as a squall line. Strong or severe thunderstorms include some of the most dangerous weather phenomena, including large hail, strong winds, and tornadoes. Some of the most persistent severe thunderstorms, known as supercells, rotate as do cyclones. While most thunderstorms move with the mean wind flow through the layer of the troposphere that they occupy, vertical wind shear sometimes causes a deviation in their course at a right angle to the wind shear direction.
Space weather is a branch of space physics and aeronomy, or heliophysics, concerned with the varying conditions within the Solar System and its heliosphere. This includes the effects of the solar wind, especially on the Earth's magnetosphere, ionosphere, thermosphere, and exosphere. Though physically distinct, space weather is analogous to the terrestrial weather of Earth's atmosphere. The term "space weather" was first used in the 1950s and popularized in the 1990s. Later, it prompted research into "space climate", the large-scale and long-term patterns of space weather.
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls from clouds due to gravitational pull. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and "precipitates" or falls. Thus, fog and mist are not precipitation; their water vapor does not condense sufficiently to precipitate, so fog and mist do not fall. Two processes, possibly acting together, can lead to air becoming saturated with water vapor: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers.
The Mauna Loa Observatory (MLO) is an atmospheric baseline station on Mauna Loa, on the island of Hawaii, located in the U.S. state of Hawaii.
The National Severe Storms Laboratory (NSSL) is a National Oceanic and Atmospheric Administration (NOAA) weather research laboratory under the Office of Oceanic and Atmospheric Research. It is one of seven NOAA Research Laboratories (RLs).
Marambio Station is a permanent, all year-round Argentine Antarctica station named after Vice-Commodore Gustavo Argentino Marambio, an Antarctic aviation pioneer. It is located in Marambio Island, Graham Land, Antarctic Peninsula, some 100 km (60 mi) from the coastal civilian village of Esperanza.
Miguel José Yacamán is a Mexican physicist who has made contributions to the fields of materials science, nanotechnology, and physics.
The Plate Boundary Observatory (PBO) was the geodetic component of the EarthScope Facility. EarthScope was an Earth science program that explored the 4-dimensional structure of the North American Continent. EarthScope was a 15-year project (2003-2018) funded by the National Science Foundation (NSF) in conjunction with NASA. PBO construction took place from October 2003 through September 2008. Phase 1 of operations and maintenance concluded in September 2013. Phase 2 of operations ended in September 2018, along with the end of the EarthScope project. In October 2018, PBO was assimilated into a broader Network of the Americas (NOTA), along with networks in Mexico (TLALOCNet) and the Caribbean (COCONet), as part of the NSF's Geodetic Facility for the Advancement of Geosciences (GAGE). GAGE is operated by EarthScope Consortium.
Convective storm detection is the meteorological observation, and short-term prediction, of deep moist convection (DMC). DMC describes atmospheric conditions producing single or clusters of large vertical extension clouds ranging from cumulus congestus to cumulonimbus, the latter producing thunderstorms associated with lightning and thunder. Those two types of clouds can produce severe weather at the surface and aloft.
Computational geophysics is the field of study that uses any type of numerical computations to generate and analyze models of complex geophysical systems. It can be considered an extension, or sub-field, of both computational physics and geophysics. In recent years, computational power, data availability, and modelling capabilities have all improved exponentially, making computational geophysics a more populated discipline. Due to the large computational size of many geophysical problems, high-performance computing can be required to handle analysis. Modeling applications of computational geophysics include atmospheric modelling, oceanic modelling, general circulation models, and geological modelling. In addition to modelling, some problems in remote sensing fall within the scope of computational geophysics such as tomography, inverse problems, and 3D reconstruction.
The Verification of the Origins of Rotation in Tornadoes Experiment are field experiments that study tornadoes. VORTEX1 was the first time scientists completely researched the entire evolution of a tornado with an array of instrumentation, enabling a greater understanding of the processes involved with tornadogenesis. A violent tornado near Union City, Oklahoma was documented in its entirety by chasers of the Tornado Intercept Project (TIP) in 1973. Their visual observations led to advancement in understanding of tornado structure and life cycles.
UNAVCO was a non-profit university-governed consortium that facilitated geology research and education using geodesy.
Google Public Alerts Site was an online notification service owned by Google.org that sends safety alerts and launched to the United States, Australia, Canada, Colombia, Japan, Taiwan, Indonesia, Mexico, and Brazil on October 30, 2012, and to the Philippines on November 12, 2014. It is part of the Google Crisis Response team and publishes content from its partners of each country. If you activate Google Now, you can see suitable weather and public safety on Google Search and Google Maps.
NOAA-11, known as NOAA-H before launch, was an American weather satellite operated by the National Oceanic and Atmospheric Administration (NOAA) for use in the National Operational Environmental Satellite System (NOESS) and for support of the Global Atmospheric Research Program (GARP) during 1978–1984. It was the fourth of the Advanced TIROS-N series of satellites. The satellite design provided an economical and stable Sun-synchronous platform for advanced operational instruments to measure the atmosphere of Earth, its surface and cloud cover, and the near-space environment.
