Buresh Blog: Very warm October.... October rainfall... check your irrigation system

We're in the last month of the Atlantic hurricane season.  Only two hurricanes - going back to 1851 - have made landfall on U.S. soil during the month of Nov.  "Yankee" hit Miami Nov. 4, 1934 & "Kate" hit the Fl. Panhandle Nov. 22, 1985.  More in "Talking the Tropics With Mike".

For the 2nd year in a row, we're having a very warm autumn.  October was the 6th warmest on record for Jacksonville & the warmest since 1981.  Every month this year so far has been above avg.:

And October was a dry month for NE Fl...  wetter for SE Ga.  From our Jax N.W.S.:

Speaking of rainfall....now that we're in standard time, residents are only allowed to water their yards & landscaping once a week.  Though typically drier this time of year, days or shorter & temps. are cooler so less water is generally needed.  From St. Johns River Management District:

Starting Sunday, Nov. 3, homeowners and businesses will fall back to once-a-week landscape irrigation across the 18 counties of the St. Johns River Water Management District. Nov. 3 is the day that Eastern Standard Time begins. "Healthy lawns in our area require no more than one day a week of irrigation during cooler weather, based on scientific analysis from the University of Florida," said St. Johns River Water Management District Executive Director Dr. Ann Shortelle. "So, when you change your clocks Saturday night, be sure to also reset your sprinkler timers to water only on the designated day for your address. And thanks for doing your part to protect Florida's water resources!"

The district's new Water Less campaign features four seasonal themes, starting with "Fall Back" in November to encourage once-a-week watering as temperatures begin cooling. Public water supply is the largest category of water use in the district's 18-county region — about 565.5 million gallons of water a day. The bulk of this water is for residential water use, and landscape irrigation can account for more than 50 percent of total water use at residential locations. Because lawns need significantly less water in Florida's winter months, watering restrictions are in place to ensure that water used for irrigation is used efficiently.

During Eastern Standard Time, landscape irrigation is limited to no more than one day a week on the following schedule:

• Saturday at addresses that end in an odd number or have no address

• Sunday at addresses that end in an even number

• Tuesday at nonresidential addresses

• No irrigation is allowed between 10 a.m. and 4 p.m.

Irrigation restrictions apply to all landscape watering not currently regulated by a consumptive use permit, which typically includes residential, commercial and industrial landscapes, and includes water withdrawn from ground or surface water, from a private well or pump, or from a public or private water utility. Golf courses, plant nurseries, agricultural crops, and sports recreational areas generally have consumptive use permits that specify their irrigation limitations.

Massive Amazon wildfires made headlines in Sept. with the typical flippant blame placed solely on climate change.  But as is often the case, there are extenuating circumstances:

A new NASA study shows that over the last 20 years, the atmosphere above the Amazon rainforest has been drying out, increasing the demand for water and leaving ecosystems vulnerable to fires and drought. It also shows that this increase in dryness is primarily the result of human activities.

Scientists at NASA's Jet Propulsion Laboratory in Pasadena, California, analyzed decades of ground and satellite data over the Amazon rainforest to track both how much moisture was in the atmosphere and how much moisture was needed to maintain the rainforest system.

"We observed that in the last two decades, there has been a significant increase in dryness in the atmosphere as well as in the atmospheric demand for water above the rainforest," said JPL's Armineh Barkhordarian, lead author of the study. "In comparing this trend to data from models that estimate climate variability over thousands of years, we determined that the change in atmospheric aridity is well beyond what would be expected from natural climate variability." 

So if it's not natural, what's causing it?

Barkhordarian said that elevated greenhouse gas levels are responsible for approximately half of the increased aridity. The rest is the result of ongoing human activity, most significantly, the burning of forests to clear land for agriculture and grazing. The combination of these activities is causing the Amazon's climate to warm.

When a forest burns, it releases particles called aerosols into the atmosphere - among them, black carbon, commonly referred to as soot. While bright-colored or translucent aerosols reflect radiation, darker aerosols absorb it. When the black carbon absorbs heat from the sun, it causes the atmosphere to warm; it can also interfere with cloud formation and, consequently, rainfall.

Why It Matters

The Amazon is the largest rainforest on Earth. When healthy, it absorbs billions of tons of carbon dioxide (CO 2 ) a year through photosynthesis - the process plants use to convert CO 2 , energy and water into food. By removing CO 2  from the atmosphere, the Amazon helps to keep temperatures down and regulate climate.

But it's a delicate system that's highly sensitive to drying and warming trends.

Trees and plants need water for photosynthesis and to cool themselves down when they get too warm. They pull in water from the soil through their roots and release water vapor through pores on their leaves into the atmosphere, where it cools the air and eventually rises to form clouds. The clouds produce rain that replenishes the water in the soil, allowing the cycle to continue. Rainforests generate as much as 80% of their own rain, especially during the dry season.

But when this cycle is disrupted by an increase in dry air, for instance, a new cycle is set into motion - one with significant implications, particularly in the southeastern Amazon, where trees can experience more than four to five months of dry season.

 

"It's a matter of supply and demand. With the increase in temperature and drying of the air above the trees, the trees need to transpire to cool themselves and to add more water vapor into the atmosphere. But the soil doesn't have extra water for the trees to pull in," said JPL's Sassan Saatchi, co-author of the study. "Our study shows that the demand is increasing, the supply is decreasing and if this continues, the forest may no longer be able to sustain itself."

Scientists observed that the most significant and systematic drying of the atmosphere is in the southeast region, where the bulk of deforestation and agricultural expansion is happening. But they also found episodic drying in the northwest Amazon, an area that typically has no dry season. Normally always wet, the northwest has suffered severe droughts over the past two decades, a further indication of the entire forest's vulnerability to increasing temperatures and dry air.

If this trend continues over the long term and the rainforest reaches the point where it can no longer function properly, many of the trees and the species that live within the rainforest ecosystem may not be able to survive. As the trees die, particularly the larger and older ones, they release CO 2  into the atmosphere; and the fewer trees there are, the less CO 2  the Amazon region would be able to absorb - meaning we'd essentially lose an important element of climate regulation.

The study, "A Recent Systematic Increase in Vapor Pressure Deficit Over Tropical South America," was published in October in Scientific Reports. The science team used data from NASA's Atmospheric Infrared Sounder (AIRS) instrument aboard the Terra satellite.

The Latest News Headlines

  • Saying it will make the facility so much better, leaders of the Florida Theatre officially launched a capital campaign to complete a $10 million renovation ahead of the 100th anniversary of the downtown landmark.   WOKV first reported about the renovation plans in July, when Mayor Lenny Curry’s budget outline offered up $1 million each of the next five years to match the Florida Theatre Performing Arts Center, Inc, which is the nonprofit that runs the historic venue. Total contribution from both parties combined at $10 million.  INDEPTH: Once in a generation - Florida Theatre looking at $10 million in renovations, upgrades To date, 72 donors have pledged or gifted $2.2 million toward the campaign that quietly began more than two years ago. The Theatre also instituted a $2.50 per ticket fee on all ticket sales that goes to restoration of the facility. That is projected to bring in approximately $1.5 million over the next five years.   “We’re a little over $7 million towards our $10 million goal as of today so we are super excited about all of this”, said Florida Theatre President Numa Saisselin.  Mayor Lenny Curry reflected on the decades of performances he has attended through the years at the Florida Theatre, and he looks forward to seeing the improvements come to fruition after funding was approved.  “Often times usually in a budget as large as ours some real jewels that are in the budget kind of get lost in the conversation so it’s good to be here today because this really is a jewel and a special nugget in the budget that we just put forward”, Curry said.   Theatre operators want to keep the same feel but install completely new seats. Plans involve better addressing ADA regulations- the seating arrangement now pre-dates those rules, according to Saisselin, so while the venue is in compliance, it is not always an ideal arrangement. Beyond that, there are a few different areas to address, with the auditorium remaining the focus. He says they want to upgrade the sound and lighting systems. Not only will this make for a more enjoyable show for you and the artist or event involved, but he says it could actually save FTPAC some money in the future, because currently, if an artist wants a certain speaker setup, the Florida Theatre may have to rent equipment, as an example. Over 3,000 people attend Florida Theatre every week, or 175,000 per year, according to Saisselin.  The work also includes renovating the bathrooms.  Air conditioning is another item on the list- updating the system so that there’s not a constant need for repairs. The iconic marquee and canopy are also in for some work, although Saisselin says they are not changing the overall look. Digital signs were recently installed at the Florida Theatre as a result of funds from a private donor, but Saisselin says there is still internal wiring work to do on the canopy, along with structural repairs. While the canopy and marquee are not original to 1927, Saisselin says he knows it’s how people recognize the venue, and they want to respect that.
  • Officials have closed all public schools in Roanoke, Virginia, as police search for a former U.S. Marine accused of killing his mother's boyfriend in nearby Franklin County. >> Read more trending news  Sheriff's deputies said Michael Alexander Brown, 22, is wanted on suspicion of shooting and killing Rodney Wilfred Brown, 54, last week at the home his mother and Brown shared in Hardy. Here are the latest updates: dfdf Update 9:30 a.m. EST Nov. 14: Officials with the U.S. Marshals Service are offering a $10,000 reward for information leading to the arrest of Michael Alexander Brown, 22. Franklin County sheriff's deputies said Brown is wanted on a charge of second-degree murder after his mother's boyfriend, 54-year-old Rodney Wilfred Brown, was found shot dead last week at his home in Hardy. Deputies said Brown deserted his post last month at Camp Lejeune in North Carolina, where he served as a combat engineer. Thursday's search was prompted by the discovery of his car on a road in Roanoke, officials said. 'It was unknown where Michael may be headed or where he has been staying since leaving his post,' deputies said Sunday in a news release. 'He has been known to live in the woods and frequent National Parks and National Forests. He is believed to be armed with a high-powered rifle and may have access to other weapons.' Deputies urged anyone with information on Brown's whereabouts to contact authorities at 540-483-6662. Update 8:17 a.m. EST Nov. 14: According to WSET, Roanoke police believe Michael Alexander Brown, who is wanted on a murder charge, was 'in the Roanoke area' and may be armed. According to NBC News, Brown, 22, is facing a second-degree murder charge in the Saturday shooting death of 54-year-old Rodney Brown. Police said Michael Brown, who had been a combat engineer at North Carolina's Camp Lejeune before he deserted last month, 'is most likely on foot and possibly looking for transportation,' WSET reported. The suspect, who is white with brown hair and blue eyes, stands 6 feet tall and weighs 145 pounds, WDBJ reported.  Original report: Police in Virginia are 'actively investigating a situation' near a Roanoke's Patrick Henry High School, authorities said early Thursday. As a result, all of the district's public schools are closed, WFXR and WDBJ are reporting. Please return for updates.
