We identified infant rumbles based on acoustic data from African elephants at Disney's Animal Kingdom (0 — 3 yrs; n = 120 rumbles), in which infants aged 0 — 2 yrs produced rumbles with mean fundamental frequencies above 20 Hz and mean durations below 1.5 sec.

If the tropopause level LW flux were ever saturated over the whole LW portion of the spectrum, and there were still significant solar heating below that level, then the tropopause would tend to shift upward to where the LW flux is not saturated at some frequencies; in an equilibrium climate, the net LW flux out of the tropopause has to balance SW heating below the tropopause (in the approximation of zero non-radiative flux out of the tropopause), and thus can not be zero.

While the water temperature in the Gulf of Mexico is recently about 4º F above average, a review of major Gulf hurricanes between 1870 and 2010 by meteorologist Roy Spencer at the University of Alabama in Huntsville revealed that they occurred with equal frequency both when conditions were below and above average.
