Oct. 6, 2017 - "Talking the Tropics With Mike" - updated every day during the hurricane season (through Nov. 30th)....
So we turn the calendars to Oct. & say "hello fall" - or at least in theory. So far, still very warm & humid, & I don't see a lot of change in that pattern or the overall wet pattern through at least mid month. Oct. averages @ JIA:
Low / High - 1st: 66 / 84; 31st: 55 / 77
SR / SS: 1st - 7:20am / 7:12pm.... 31st - 7:40am / 6:40pm - lose 52 min. of daylight.
Oct. night skies courtesy SkyandTelescope:
Oct. 8–9 (late evening): The waning gibbous Moon shines with the Hyades and Aldebaran.
Oct. 15 (morning): The waning crescent Moon occults (covers) the star Regulus for much of the United States.
Oct. 20–22 (morning): The modest Orionid meteor shower is active before dawn’s first light.
Oct. 17 (dawn): A super-thin waning crescent Moon hangs above Venus and just left of faint Mars. Look very low in the east as dawn brightens. Binoculars will help.
Oct. 23 (dusk): Saturn shines fairly low in the southwest, about 6° left of the waxing crescent Moon.
Oct. 24 (evening): The crescent Moon, thicker now, is about 6° upper left of Saturn.
Nov. 4 (dawn): Spica shines 4° right of Venus very low in the east-southeast. Bring binoculars. Faint Mars shines some 16° above Spica.
Nov. 5: Daylight-saving time ends at 2 a.m. for most of the U.S. and Canada.
Nov. 5–6 (night): A waxing gibbous Moon occults (covers) Aldebaran for much of North America and northern Europe.

As part of an ongoing joint project between UAH, NOAA and NASA, Christy and Dr. Roy Spencer, an ESSC principal scientist, use data gathered by advanced microwave sounding units on NOAA and NASA satellites to get accurate temperature readings for almost all regions of the Earth. This includes remote desert, ocean and rain forest areas where reliable climate data are not otherwise available.
The satellite-based instruments measure the temperature of the atmosphere from the surface up to an altitude of about eight kilometers above sea level.
September temperatures (preliminary)
Global composite temp.: +0.54 C (about 0.97 degrees Fahrenheit) above 30-year average for September.
Northern Hemisphere: +0.51 C (about 0.92 degrees Fahrenheit) above 30-year average for September.
Southern Hemisphere: +0.57 C (about 1.03 degrees Fahrenheit) above 30-year average for September.
Tropics: +0.53 C (about 0.95 degrees Fahrenheit) above 30-year average for September.
August temperatures (revised):
Global Composite: +0.41 C above 30-year average
Northern Hemisphere: +0.40 C above 30-year average
Southern Hemisphere: +0.41 C above 30-year average
Tropics: +0.46 C above 30-year average
(All temperature anomalies are based on a 30-year average (1981-2010) for the month reported.)
Notes on data released Oct. 2, 2017:
Boosted by warmer than normal water in the equatorial eastern Pacific Ocean that peaked in June and July, global average temperatures in the atmosphere rose to record levels in September, according to Dr. John Christy, director of the Earth System Science Center at The University of Alabama in Huntsville. Not only was it the warmest September on record, it was also the warmest month (compared to seasonal norms) in the 38-year satellite temperature record that wasn’t associated with an “officially recognized” El Niño Pacific Ocean warming event.
Of the 20 warmest monthly global average temperatures in the satellite record, only September 2017 was not during an El Niño. Compared to seasonal norms, the global average temperature in September made it the ninth warmest month in the satellite record.
