weather patterens Crossword

the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.:
the state or quality of being humid.
the weather conditions prevailing in an area in general or over a long period:
the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at the same temperature.
The dew point (dew point temperature or dewpoint) is the temperature at which dew forms and is a measure of atmospheric moisture.
Surface of separation of two air masses.
a system of winds rotating inward to an area of low atmospheric pressure, with a counterclockwise (northern hemisphere) or clockwise (southern hemisphere) circulation; a depression.
a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system.
a body of air with horizontally uniform temperature, humidity, and pressure.
air mass is an air mass formed over land in a cold region with cold dry air.
air coming originally from polar regions but having humidity and temperature properties modified by passing over relatively warm oceans.
a weather system with high atmospheric pressure at its center, around which air slowly circulates in a clockwise (northern hemisphere) or counterclockwise (southern hemisphere) direction.
the boundary of an advancing mass of cold air, in particular the trailing edge of the warm sector of a low-pressure system.
a weather condition in which the boundary between a cold air mass and a warm air mass is stationary
a composite front produced by occlusion.
a storm with a violent wind, in particular a tropical cyclone in the Caribbean.
a storm with thunder and lightning and typically also heavy rain or hail.
an instrument for measuring and indicating temperature, typically one consisting of a narrow, hermetically sealed glass tube marked with graduations and having at one end a bulb containing mercury or alcohol that expands and contracts in the tube with heating and cooling.
an instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude.
an instrument for measuring the speed of the wind, or of any current of gas.
