Across
the variable frontal zone of middle latitudes separating air masses of polar and tropical origin.
occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain.
the heat required to convert a solid into a liquid or vapor, or a liquid into a vapor, without change of temperature.
a reversal of the normal decrease of air temperature with altitude, or of water temperature with depth.
the conversion of a vapor or gas to a liquid.
a seasonal prevailing wind in the region of South and Southeast Asia, blowing from the southwest between May and September and bringing rain, or from the northeast between October and April.
an instrument for measuring the humidity of the air or a gas.
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.
the belt of prevailing westerly winds in the mid-latitudes of the northern and southern hemispheres.
the atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form.
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.
Down
the process of turning from liquid into vapor.
a narrow variable band of very strong predominantly westerly air currents encircling the globe several miles above the earth.
the force exerted onto a surface by the weight of the air.
the geological process in which sediments, soil and rocks are added to a landform or land mass.
rain, snow, sleet, or hail that falls to the ground.
tiny suspended particle, either solid or liquid, upon which water vapour condenses in the atmosphere.
a wind blowing steadily towards the equator from the northeast in the northern hemisphere or the southeast in the southern hemisphere, especially at sea.
The boundary between two air masses that have different temperatures or humidity.
to convert (a solid substance) by heat into a vapor, which on cooling condenses again to solid form, without apparent liquefaction.
a body of air with horizontally uniform temperature, humidity, and pressure.
an instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude.
