Dipole model of the Earth's magnetic field (MLAT), or geomagnetic latitude, formula_10 is measured northwards from the equator (analogous to geographic latitude) and is related to formula_9 by formula_12. In this case, the radial and azimuthal components of the magnetic field (the latter still in the formula_9 direction, measured from the axis of the north pole) are given by formula_14 formula_15 formula_16 where formula_17 in this case has units of Earth radii (formula_18). Invariant latitude is a parameter that describes where a particular magnetic field line touches the surface of the Earth. It is given by formula_19 or formula_20 where formula_21 is the invariant latitude and formula_22
The Longest Winter was decorated, including four Distinguished Service Crosses, five Silver Stars, and ten Bronze Stars with V for Valor, making the platoon America's most decorated of World War II. The Longest Winter The Longest Winter: The Battle of the Bulge and the Epic Story of World War II's Most Decorated Platoon is a non-fiction book written by Alex Kershaw and published in 2004 by Da Capo Press.
