A weather instrument that measures the wind speed.
An instrument that measures air pressure.
A visible collection of tiny water droplets or, at colder temperature, ice
crystals floating in the air above the surface. There are 3 types of
clouds: Cumulus, Cirrus, and Stratus
Water that forms on objects close to the ground when its temperature
falls below the dew point of the surface air.
The process of changing a liquid to a vapor. Evaporation is part of the
water cycle.
A boundary between two different air masses, resulting in stormy
weather. A front usually is a line of separation between warm and cold
air masses
The heating effect of the Earth’s atmosphere. The atmosphere acts like
a greenhouse because sunlight freely passes through it and warms the
surface.
A form of precipitation that falls from the sky as pellets of ice. The
pellets can range in size from small pea-sized pellets, to hailstones as
large as a grapefruit.
Water in the solid phase below 32 degrees Fahrenheit
a fast flowing, river of air found in the atmosphere at around 12 km
above the surface of the Earth just under the tropopause.
A front where the warm air descends the frontal surface, except in the
low layers of the atmosphere.
An enormous and very hot spark of electricity produced by
thunderstorms. The lightning bolt itself can heat the air through which
it travels to 54,000 degrees Fahrenheit
A scientist who studies and predicts weather. Meteorologists use
sophisticated equipment, like Doppler radar and supercomputers to
predict the weather.
The federal agency that provides weather, hydrologic, and climate
forecasts and warnings for the United States.
A combination of two fronts that form when a cold front catches up
and overtakes a warm front. An occluded front is represented as a
purple line with teeth and half circles.
Any and all forms of “water” in liquid or solid form that falls from the
sky. Precipitation can be in the form of rain, drizzle, sleet, snow, and
hail.
Also known as QPF. A spatial and temporal precipitation forecast that
will predict the potential amount of future precipitation for a specified
region, or area.
Liquid precipitation in the form of water droplets greater than 0.5mm.
Precipitation that is composed of white ice crystals that fall from
clouds. Snow may stick together to form snowflakes, which have
hexagonal or six-sided shape.
An instrument used for measuring temperature. The different scales
used in meteorology are Celsius, Fahrenheit, and Kelvin or Absolute.
A small-scale current of with vertical motion. If there is enough
moisture, then it may condense, forming, a cumulus cloud, the first
step towards thunderstorm development.
An anabatic wind, it is formed during the day by the heating of the
valley floor. As the ground becomes warmer than the surrounding
atmosphere, the lower levels of air heat and rise, flowing up the
mountainsides. It blows in the opposite direction of a mountain breeze.
The state of the atmosphere at a specific time and with respect to its
effect on life and human activities. It is the short term variations of the
atmosphere. It is often referred to in terms of brightness, cloudiness,
humidity, precipitation, temperature, visibility, and wind,
The portion of the electromagnetic spectrum that has a very short
wave length. It has a wave length longer than gamma rays, yet shorter
than visible light. X-rays can penetrate various thicknesses of all solids,
and when absorbed by a gas, can result in ionization.
Snow that is given golden or yellow appearance by the presence of pine
or cypress pollen in it. I know that is not what you were thinking!
The flow of air along a latitudinal component of existing flow, normally
from west to east
