dispersion : 分散 the action or process of distributing things or people over 
                  a wide area 
divergence : In vector calculus, divergence is a vector operator that measures 
                 the magnitude of a vector field's source or sink at a given point, in 
                 terms of a signed scalar. More technically, the divergence represents 
                 the volume density of the outward flux of a vector field from an 
                 infinitesimal volume around a given point. 

entropy : 化學及热力学中所指的熵^[3]，是一種測量在動力學方面
       不能做功的能量總數，也就是當總體的熵增加，其做功能力也下降，
       熵的量度正是能量退化的指標。熵亦被用於計算一個系統中的失序現象，
       也就是計算該系統混亂的程度。 
       熵的概念是由德國物理學家克勞修斯於1865年所提出。克氏定義
       一個熱力學系統中熵的增減：在一個可逆性程序裡，被用在恆溫的熱的總數（δQ），
      並可以公式表示為：
       
       克勞修斯對變數S予以「熵」（英语：entropy）一名，希臘語源意
       為「內向」，亦即「一個系統不受外部干擾時往內部最穩定
       狀態發展的特性」^[4]。
geocentric : 地心 having or representing the earth as the center, as in former
         astronomical systems.
geographic : 地理
geopotential : 位势
geostrophic : 地转 relating to or denoting the component of a wind or current that arises 
             from a balance between pressure gradients and Coriolis forces 
geostrophy :  地转
graupel : Heavily rimed snow particles, often called snow pellets; often
                   indistinguishable from very small soft hail except for the size convention
                   that hail must have a diameter greater than 5 mm.

Sometimes distinguished by shape into conical, hexagonal, and lump (irregular) graupel.

gravitational : 引力
gravity : 重力 
gravitational potential :  is equal to the work (energy transferred) per unit mass that is 
        done by the force of gravity to move an object to a fixed reference location. 
       The reference location, where the potential is zero, is by 
        convention infinitely far away from any mass, resulting in a negative potential 
        at any finite distance.
Hecto Pascal (hPa) :  a unit for pressure, and, in this web site, used mainly for
             representing the central pressure of a typhoon. In Japan, the unit of
            "millibar" (mb) was used through November 1992, but since December 1992,
             the unit of "hectopascal" (hPa) has been used to comply with the International
            System of Units. Conversion between those two units is 1hPa = 1mb,
            however, so the value itself is the same as before.
homogeneous : 同质 of the same kind; alike.
hydrometeor : 水凝   an atmospheric phenomenon or entity involving water or water vapor,
             such as rain or a cloud.
inhibition : 抑制
isobar : A line of equal or constant pressure; an isopleth of pressure.
isobaric : 等压

iostherm : A line of equal or constant temperature.

isoheight / contour line : (Also called contour, isohypse, isoheight.) A line of
            constant elevation above a certain reference level (usually mean sea level) on a
            previously defined surface, which may be the earth's surface,
           a constant-pressure surface, an isentropic surface, etc.
iso : 异
isotropic : 各向同性 (of an object or substance) having a physical property that has
              the same value when measured in different directions.

isobaric :  等压 equal or constant pressure, with respect to either space or time.
isotherm : 等温线 equal temperature
isotropic : 各向同性

kinematic : (noun.) movement

Knot : a unit for speed. One knot means a speed of moving one nautical mile (nm) in one hour.
           Knot is used for representing the maximum wind speed at the center of a typhoon,
           or a movement speed of a typhoon on this website. Because 1nm = 1.852km,
          1kt = 1.852km/h = 0.5144m/s. Roughly speaking, halving the knot makes the speed
           in meter per second, while doubling it makes the speed in kilometer per hour.

linear : we are estimating a value for intercept (a) and the slop (b) that are raised only to
            the power 1. ( unbiased ) if we repeat the estimation with new samples, we
            will likely find different values for b.  If we do so, we can then calculate the
            average of all of these bs. If it is true that the average of the bs is equal to the
            population's true beta (standardized b), then the estimator is said to be unbiased;
           similarly for a, the intercept term.
LTE : local thermodynamic equilibrium

mean sea level : (Abbreviated MSL; popularly called sea level.) The arithmetic mean of
           hourly heights observed over some specified period. In the United States, mean
           sea level is defined as the mean height of the surface of the sea for all stages
            of the tide over a 19-year period. Selected values of mean sea level serve
           as the sea level datum for all elevation surveys in the United States. In 

           meteorology, mean sea level is used as the reference surface for all altitudes in upper-

           atmospheric work; in aviation it is the level above which altitude is measured by a  

           pressure altimeter. Along with mean high water, mean low water, and mean lower low 

           water, mean sea level is a type of tidal datum ( standard ).
moist : 潮湿

occluded front :  http://www.athensgaweather.com/meteorology-101-pressure-fronts/
perpendicular : 垂直 at an angle of 90° to a given line, plane, or surface.pendicular : 相垂直
predictor : x in regression equation y = ax + b
predictand : y in regression equation y = ax + b 
prognostic : 前兆serving to predict the likely outcome of a disease or 
           ailment; of or relating to a medical prognosis. 
quasi : 准 seemingly; apparently but not really.
quasi-geostropic : 准地转
Quantitative Precipitation Forecasts: QPF:
            The Quantitative Precipitation Forecast (abbreviated QPF) is the expected
            amount of melted precipitation accumulated over a specified time period over a
            specified area. A QPF will be created when precipitation amounts reaching a
            minimum threshold are expected during the forecast's valid period.
radian : 弧度 a unit of angle,  equal to an angle at the center of a circle
             whose arc is equal in length to the radius.  s = r . theta
radiance : 1. light or heat as emitted or reflected by something.
                2. the flux of radiation emitted per unit solid angle in a given direction
                   by a unit area of a source.
regression : a measure of the relation between the mean value of one variable
           (e.g., output) and corresponding values of other variables (e.g., time and cost).
regression analysis : In statistics, it is a statistical process for estimating the relationships
             among variables. It includes many techniques for modeling and analyzing
            several variables, when the focus is on the relationship between a dependent variable
            and one or more independent variables. More specifically, regression analysis
            helps one understand how the typical value of the dependent variable
            (or 'criterion variable') changes when any one of the independent variables is
            varied, while the other independent variables are held fixed.
sea level pressure : The atmospheric pressure at mean sea level, either directly          measured or, most commonly, empirically determined from the observed
         station pressure. In regions where the earth's surface is above sea level, it is
         standard observational practice to reduce the observed surface pressure to the
        value that would exist at a point at sea level directly below if air of a temperature
        corresponding to that actually present at the surface were present all the way
        down to sea level. In actual practice, the mean  temperature for the preceding
        12 hours is employed, rather than the current temperature. This
        "reduction of pressure to sea level" is responsible for many anomalies

         in the pressure field in mountainous areas on the surface synoptic chart.

standardized coefficient : Before solving a multiple regression problem, all variables
         (independent and dependent) can be standardized. Each variable can be
          standardized by subtracting its mean from each of its values and then
         dividing these new values by the standard deviation of the variable.
         Standardizing all variables in a multiple regression yields standardized
         regression coefficients that show the change in the dependent variable
         measured in standard deviations.
stratification : 分层 demixing, lamination
thermal : 热 
thermodynamics :  热力学 the branch of physical science that deals with the relations
            between heat and other forms of energy (such as mechanical, electrical,
           or chemical energy), and, by extension, of the relationships between all forms of
           energy.
trajectory : 轨迹 the path followed by a projectile flying or an object moving under
                the action of given forces.
