What is dry static energy?
(Also called the Montgomery streamfunction.) A thermodynamic variable similar to potential temperature, except that the concept of static energy assumes that any kinetic energy is locally dissipated into heat. The amount of this dissipative heating is often negligible.
What is the purpose of moist static energy?
The moist static energy is a combination of a parcel’s enthalpy due to an air parcel’s internal energy and energy required to make room for it, its potential energy due to its height above the surface, and the latent energy due to water vapor present in the air parcel.
What is moist static stability?
A new effective static stability is derived that fundamentally captures the effect of latent heat release on moist eddy circulations. It differs from the usual dry static stability by an additive term that depends on temperature and a parameter measuring the up–down asymmetry of vertical velocity statistics.
What two quantities are conserved for a dry adiabatic process?
For dry adiabatic processes, the water vapor mixing ratio, q, is conserved, so dq = 0, and therefore, dh = ds + Ldq = 0, and h is also conserved.
Is static a energy?
Static electricity is an imbalance of electric charges within or on the surface of a material. Static electricity is named in contrast with current electricity, which flows through wires or other conductors and transmits energy.
What is latent heat of vaporization of water?
Latent heat of vaporization is a physical property of a substance. It is defined as the heat required to change one mole of liquid at its boiling point under standard atmospheric pressure. It is expressed as kg/mol or kJ/kg. The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol.
Is moist static energy conserved?
Here, in computing the lifting-parcel buoyancy, the moist static energy is used as a conserved variable for the lifting parcel.
What is positive static stability?
Positive static stability is the initial tendency to return to an undisturbed state after a disturbance. This concept is easily illustrated by the ball and bowl analogy.
What happens to dry air as it is lifted adiabatically?
In scientific terms, the initial lifting of the stable low level dry air by the terrain causes the air to adiabatically expand and reach saturation, at which point the environment is unstable to moist lifting and convection is the result.
What is a dry adiabatic process?
An adiabatic process in a hypothetical atmosphere in which no moisture is present. An adiabatic process in which no condensation of its water vapor occurs and no liquid water is present.
Can static electricity hurt you?
You might even see a spark if the discharge of electrons is large enough. The good news is that static electricity can’t seriously harm you. Your body is composed largely of water and water is an inefficient conductor of electricity, especially in amounts this small. Not that electricity can’t hurt or kill you.
What is an example of static energy?
Static electricity is the result of an imbalance between negative and positive charges in an object. For example, if you rub your shoe on the carpet, your body collects extra electrons. The electrons cling to your body until they can be released. As you reach and touch your furry friend, you get a shock.
