Weather Weather The adiabatic lapse rate is the rate of temperature change that occurs in an atmosphere as a function of elevation, assuming that air behaves adiabatically. This term is most commonly used to refer to Earth's atmosphere. ...more on Wikipedia about "Adiabatic lapse rate"
In meteorology, an airmass or air mass is a large volume of air having fairly uniform characteristics of temperature, atmospheric pressure, and water vapor content. Air masses cover many hundreds or thousands of square miles, and slowly change in accordance with the terrain they are over. ...more on Wikipedia about "Air mass"
In meteorology, an anticyclone (i.e. opposite to a cyclone) is a weather phenomenon in which there is a descending movement of the air and a relative increase in barometric pressure over the part of the earth's surface affected by it. At the surface the air tends to flow outwards in all directions from the central area of high pressure, and is deflected on account of the earth's rotation (see Ferrel's law) so as to give a spiral movement. In the northern hemisphere an anticyclone rotates in the clockwise direction, while it rotates counterclockwise in the southern hemisphere. The rotation is caused by the movement of colder higher pressure air that is moving away from the poles towards the equator being affected by the rotation of the earth. Since the air in an anticyclone is descending, it becomes warmed and dried, and therefore transmits radiation freely whether from the sun to the earth or from the earth into space. Hence in winter anticyclonic weather is characterized by clear air with periods of frost, causing fogs in towns and low-lying damp areas, and in summer by still cloudless days with gentle variable airs and fine weather. ...more on Wikipedia about "Anticyclone"
Apparent wind is the breeze felt by an observer. It is created both by the movement of the observer, and by the true wind. For a stationary observer, both apparent wind and true wind are the same. Apparent wind is calculated by the sum of two vectors. The first vector is the true wind velocity. The second vector is the velocity of the observer. By adding these two vectors together, one can determine the apparent wind. ...more on Wikipedia about "Apparent wind"
Arctic cyclones are vast areas of low pressure. They should not be confused with what are commonly referred to as polar lows that behave similarly to hurricanes. ...more on Wikipedia about "Arctic cyclone"

A cloudburst is extreme rainfall, sometimes mixed with hail and thunder, which normally lasts no longer than a few minutes but is capable of creating minor flood conditions. Cloudbursts descend from very high clouds, sometimes with tops above 15 kilometers. The monsoon rains during July and August put a lot of water into the Himalayan soil; when there are instances of cloudbursts, the results can be disastrous. ...more on Wikipedia about "Cloudburst"
In meteorology, convective available potential energy (CAPE) is the amount of energy a parcel of air would have if lifted a certain distance vertically through the atmosphere. CAPE is measured in joules per kilogram of air (J/kg). Any value greater than 0 J/kg indicates instability and the possibility of thunderstorms. ...more on Wikipedia about "Convective available potential energy"
Convective inhibition (CIN or CINH) is a meteorological parameter that measures the amount of energy that will prevent an air parcel from rising from the surface to the level of free convection. Conceptually, it is the opposite of CAPE. ...more on Wikipedia about "Convective inhibition"
In meteorology, a cyclone is the rotation of a volume of air about an area of low atmospheric pressure. Cyclones are responsible for a wide variety of different meteorological phenomena such as tropical cyclones and tornadoes. Because of this, most weather forecasters avoid using the term cyclone without a qualifying term. ...more on Wikipedia about "Cyclone"
The density of air, ρ (Greek: rho) (air density), is the mass per unit volume of Earth's atmosphere, and is a useful value in aeronautics. In the SI system it is measured as the number of kilograms of air in a cubic meter (kg/m3). At sea level and at 20 °C dry air has a density of approximately 1.2 kg/m3. varying with pressure and temperature. Air density and air pressure decrease with increasing altitude. ...more on Wikipedia about "Density of air"

"Devil's beatin' his wife" is an expression which refers to rain while the sun shines. This expression is common in the southeastern United States. The rain represents the tears of the Devil's wife. This phenomenon has other names elsewhere in the world, such as sunshower. These conditions often lead to the appearance of a rainbow. ...more on Wikipedia about "Devil's beatin' his wife"
The dry season is a term commonly used when describing the weather in the tropics. The weather in the tropics is dominated by the tropical rain belt, which oscillates from the northern to the southern tropics over the course of the year. The tropical rain belt lies in the southern hemisphere roughly from October to March, and during this time the northern tropics experience a dry season in which precipitation is very rare, and days are typically hot and sunny throughout. From April to September, the rain belt lies in the northern hemisphere, and the southern tropics experience their dry season. ...more on Wikipedia about "Dry season"
An easterly wave is a trough of low atmospheric pressure that is located in the tropical areas of the earth on ocean areas. Easterly waves move from the east towards the west. The wind in an easterly wave is cyclonic, however, no closed circulation exists in an easterly wave. ...more on Wikipedia about "Easterly wave"

A flood (in Old English flod, a word common to Teutonic languages; compare German Flut, Dutch vloed from the same root as is seen in flow, float) is an overflow of water, an expanse of water submerging land, a deluge. In the sense of "flowing water", the word is applied to the inflow of the tide, as opposed to the outflow or "ebb". ...more on Wikipedia about "Flood"
Fog is a cloud in contact with the ground. It occurs when moisture from the surface of the Earth evaporates; as this evaporated moisture moves upward, it cools and condenses into the familiar phenomenon of fog. Fog differs from cloud only in that fog touches the surface of the Earth, while clouds do not. It can form in a number of ways, depending on how the cooling that caused the condensation occurred: ...more on Wikipedia about "Fog"

Frost, like snow, is the result of deposition of water vapor in saturated air. If solid surfaces in contact with the air are chilled below the deposition point (see frost point), then spicules of ice grow out from the solid surface. The size of the crystals depends on time and the amount of water vapor available. ...more on Wikipedia about "Frost"
A high, high-pressure cell, or high pressure area is a region where the atmospheric pressure is greater than the surrounding area. In some countries, these regions may be referred to as anticyclones. Highs are frequently associated with light winds and subsidence. Subsidence will generally evaporate most cloud droplets after less than 500 meters, due to adiabatic heating. Thus, high pressure typically brings clear skies. During the day, since no clouds are present to reflect ...more on Wikipedia about "High pressure area"
A Hot Tower is a high cloud with plenty of rainfall found in hurricanes. Recently the National Aeronautics and Space Administration (NASA) has discovered that these hot towers appear when the hurricane is about to intensify. Kelley and Stout at NASA define a "hot tower" as a rain cloud that reaches at least to the top of the troposphere, the lowest layer of the atmosphere. It extends approximately nine miles (14.5 km) high at the tropics. These towers are called "hot" because they rise high due to the large amount of latent heat. Water vapor releases this latent heat as it condenses into liquid. ...more on Wikipedia about "Hot tower"
The humid continental climate is found over large areas of land masses in the temperate regions of the mid latitudes where there is a zone of conflict between polar and tropical air masses. The humid continental climate is marked by variable weather patterns and a large temperature range. The seasonal temperature variance can be as great as 25 to 35 degrees Celsius (45 to 63 degrees Fahrenheit). The temperature difference between the warmest and coldest months increases inland, away from the moderating influence of the ocean. ...more on Wikipedia about "Humid continental"
