Precise mathematical modelling of snowmelt is therefore challenging, with the precise influence of the controlling factors difficult to deduce. For example, snow cover evolution within high-elevation landscapes depends on the density, grain size, and microstructure of snow, the mass and timing of ...
The location of the 56 stars are identified by the initial letter of the Chinese asterism (W, D, Y, Z, S, B, L, and X) within which they are located. Also shown in Figure 4a are the positions of lunar halos with radii of 22° and 46° at 18.72 h LT. Figure 4 (a, top)...
