2025年1月28日 · National Weather Service (NWS) provides weather, hydrologic, and climate forecasts and warnings for the United States, its territories, adjacent waters and ocean areas, for the protection of life and property and the enhancement of the national economy.

Meteorological phenomena are described and quantified by the variables of Earth's atmosphere: temperature, air pressure, water vapour, mass flow, and the variations and interactions of these variables, and how they change over time. Different spatial scales are used to describe and predict weather on local, regional, and global levels.

This global web site presents OFFICIAL weather forecasts and climatological information for selected cities supplied by National Meteorological & Hydrological Services worldwide.

Meteorology The science dealing with the atmosphere and its phenomena. A distinction can be drawn between meteorology and climatology, the latter being primarily concerned with average, not actual, weather conditions.

2024年12月9日 · To understand weather, meteorologists study atmospheric patterns. The most familiar atmospheric pattern that drives weather and climate is convection, the process of warmer air rising, and colder, denser air sinking. Convection results in a transfer of energy, heat, and moisture—the basic building blocks of weather.

2025年1月3日 · Climate, conditions of the atmosphere at a particular location over a long period of time; it is the long-term summation of the atmospheric elements (and their variations) that, over short time periods, constitute weather. These elements are …

2023年10月19日 · Beyond weather forecasting, meteorology is concerned with long-term trends in climate and weather, and their potential impact on human populations. An important area of meteorological research these days is climate change and the effects it may cause. Many people wonder why the study of the atmosphere is called meteorology.
