Aids to interpreting plots:
||The long-term average of a given variable, often the 30-year period
||The difference between the observed value of a variable and its climatological
||A 5-day average of a variable, starting from 1-5 Jan, 6-10 Jan, ...,
27-31 Dec. On plots using pentad data, the date for the "middle"
of the pentad is displayed: 3 Jan, 8 Jan, ... , 29 Dec.
||The abbreviation for "hectopascal", a unit of atmospheric pressure.
For comaprison, the atmospheric pressure near the earth's surface is roughly
1000 hPa (its less at higher elevations). The 250 hPa level in the
atmosphere is roughly 10 km above the earth's surface. One hPa equals
one "millibar" or "mb", these pressure units are also displayed on some
