A semigroup is defined as a set equipped with an associative binary operation. The trivial semigroup is the simplest form of a semigroup, consisting of a single element.

Meteorological research institutes are organizations or facilities dedicated to the study of meteorology, which is the science of the atmosphere and its phenomena, particularly weather and climate. These institutes conduct research, provide data and forecasts, and develop models to understand atmospheric processes and their effects on the environment and human activities. Their work often encompasses various fields including: 1. **Weather Forecasting**: Developing models to predict weather patterns and conditions.

Regional Specialized Meteorological Centres (RSMCs) are specialized units within the World Meteorological Organization (WMO) framework that focus on specific aspects of meteorology, climatology, and hydrology for a defined region. They play a key role in providing timely and accurate weather forecasts, including warnings for severe weather events, as well as information related to climate and environmental monitoring.

The Center for Southeastern Tropical Advanced Remote Sensing (CSTARS) is a research and development center affiliated with the University of Miami’s Rosenstiel School of Marine and Atmospheric Science. CSTARS focuses on utilizing advanced remote sensing techniques and technologies to study and monitor various environmental and atmospheric phenomena, particularly in the southeastern United States and the tropical regions. CSTARS employs satellite imagery and other remote sensing data to conduct research in areas such as climate change, weather forecasting, marine environments, and disaster response.

The European Centre for Medium-Range Weather Forecasts (ECMWF) is an independent intergovernmental organization supported by 34 European countries. It is renowned for its advanced numerical weather prediction and research capabilities. Founded in 1975, ECMWF focuses on providing medium-range weather forecasts, which typically cover a timeframe of around 3 to 15 days ahead.

The Global Climate Observing System (GCOS) is an international program established to ensure that comprehensive, long-term climate observations are collected and made available for the assessment of climate change and its impacts. GCOS is coordinated by the World Meteorological Organization (WMO), in collaboration with various international organizations and stakeholders involved in climate observation and research.

The Global Observing Systems Information Center (GOSIC) is a component of the Global Observing System (GOS) initiative, which aims to provide comprehensive data and information related to the global environment, climate, and weather patterns. It serves as a centralized repository and dissemination platform for observing system data from various sources, including satellites, ground-based stations, and other monitoring systems.

Meteomont is a meteorological and environmental monitoring system specifically designed for mountainous areas. It is commonly used in regions prone to snow and avalanche activity. The system provides real-time weather data, including temperature, humidity, wind speed, and precipitation, which are essential for assessing avalanche risks and other snow-related hazards. Developed in Italy, Meteomont integrates data collection from various weather stations located in mountainous regions, allowing for improved weather forecasting and hazard assessment.

The Pacific Islands Ocean Observing System (PIOOS) is a regional component of the larger U.S. Integrated Ocean Observing System (IOOS). PIOOS focuses on the Pacific Islands region, which includes territories and nations in the central and western Pacific Ocean. Its primary aim is to promote ocean and coastal management, research, and education by providing real-time data and information about oceanic and atmospheric conditions.

TORRO can refer to various things depending on the context, but one of the most common references is to the TORRO scale, which is a classification system used for measuring the intensity of tornadoes. The TORRO scale ranges from T0 (the weakest) to T11 (the strongest), with different levels indicating the potential damage and effects associated with the tornado. Another possibility could be TORRO, which may refer to specific organizations, products, or other entities with that name.

The World Meteorological Organization (WMO) is a specialized agency of the United Nations responsible for coordinating international cooperation in meteorology (weather and climate), climatology, hydrology, and related fields. It was established in 1950 and operates out of its headquarters in Geneva, Switzerland. The WMO's primary objectives include: 1. **Providing Weather and Climate Services**: The organization helps member countries improve their weather, climate, water, and environmental services by providing technical support and guidance.

World Weather Attribution (WWA) is a collaborative research initiative that focuses on analyzing the influence of climate change on specific weather events. It aims to provide timely and rigorous assessments of how climate change may have affected the likelihood or intensity of extreme weather phenomena, such as heatwaves, heavy rainfall, or droughts. The organization combines expertise from climate scientists and meteorologists from various institutions around the world.

Atmospheric electricity refers to the electric charges and electric fields present in the Earth's atmosphere. This phenomenon encompasses various processes and phenomena, including: 1. **Thunderstorms and Lightning**: One of the most familiar aspects of atmospheric electricity is the generation of lightning. Thunderstorms create significant electrical charge separation between different parts of the cloud and between the cloud and the ground. Lightning occurs as a discharge of this accumulated electrical energy.

Snow and ice weather phenomena refer to atmospheric conditions that involve the formation, presence, and effects of snow and ice. These phenomena typically occur in cold weather conditions and can result from various factors, including temperature, humidity, and atmospheric pressure. Here are some key aspects of snow and ice weather phenomena: ### Snow 1. **Formation**: Snow forms when water vapor in the atmosphere cools and condenses into ice crystals.

An "airshed" refers to a specific geographic area that shares the same air quality and is impacted by the same sources of air pollution.
