Ground Temperature vs. Air Temperature

Since we are having cold spells all around the world lately (Australia, West + East Coast of Northern America, Werstern Europe etc...), I'm thinking a lot about a subject that from my perception is not so often discussed around palmnuts and exotic growers and I catch myself every now an then not taking it into consideration: The difference between the measured temperature at 2m above the ground and the temperature next to the soil. Especially in the winter this can mean dead or alive for some smaller plants like overhead protection or exposure can. I think it is an interesting topic because like all of the other climate parameters it's not universal and it can differ a lo…

Hi Everyone, I am curious what the rest of you have to say about next week's cold blast here in North America? What are your gut feelings and analysis of the situation? From what I have seen and heard, there have been fluctuations going back and forth from warmer to colder, and some discrepancy between the American and European Models. John

Oregon heat and drought stress on forests.
by Chester B- 4 replies

It’s an interesting read and backs up my own anecdotal observations/conclusions. It’s common to see more dead and dying native conifers each year. Also many of the trees commonly planted in the east or areas with regular rainfall suffer through our summers. https://www.nbcnews.com/news/amp/rcna59671

UK Worst Freeze Since 2010 1 2 3
by Foxpalms- 3 followers
- 117 replies

The Polar vortex is sending freezing air towards the UK creating a cold setup quite possibly worse than the 2010 freeze. All the air from the arctic is being funneled down onto us. We are under clear skies all night tonight the temperature in London is slowly dropping whilst the countryside and the outskirts are plummeting in temperature. This freeze has practically appeared out of nowhere after a long hot summer and warm autumn/fall. It was supposed to be just above freezing however the last week the forecast got worse and worse until we ended up with this, an arctic air mass and clear skies at night. This is the worst possible scenario whilst snow might also be bad the…

Help me understand this!
by ahosey01- 2 replies

This fall, I got a weather station in my yard. I am at the bottom of a river valley in the desert, and my neighborhood is full of large trees (cottonwoods, pecans, ash trees, cypresses, etc.) because the groundwater is so close to the surface. Many of these trees are not on irrigation and they look beautiful. Anyways - because we're in this valley (and in the desert) the cold air seems to sink down to my property. I find that every night, I am between 28F and 33F. What's unusual, though, is that my temperatures appear inversely related to the rest of Wickenburg. In the morning, when I check my station, I check the local Weather Underground ones also. What I…

I am attempting to understand an anomaly that I have observed in temperature recording stations near Lake Havasu, Arizona (Bullhead City Airport)and Yuma, Arizona. Bullhead City, Arizona is located at latitude 35.15° north and is 547 feet in altitude. The location at Yuma, Arizona is located at latitude 32.97° north with an elevation of 200 feet. Notwithstanding this rather substantial difference in latitude, Bullhead City, Arizona is consistently warmer in the winter months compared to areas surrounding Yuma, Arizona. One prime example is during the 2007 January freeze experienced throughout the western United States. Bullhead City, Arizona (Airport) recorded a low …

Is it me or are we already way cooler than we should be for early November. I’ve been in the low 40s for lows for over a week now. It’s having a hard time hitting 70 during the day. Hope we don’t have a bad winter.

Best website for historic low temperatures
by Cody Salem- 2 replies
- 428 views
I've been lurking at this website for years and decided that I should start doing some posting. I wanted to share what I have found to be the easiest place to find data historic low temperatures across the U.S. It's pretty obscure, so I doubt many of you have seen it before. https://wrcc.dri.edu/summary/sodusa.html First choose your state, then you will see a list view and map view of all the available stations. Some stations have more complete data than others, so you might have to check a few of them. Even though the website format is a little outdated, the data is auto-generated, so all of the stations that are a…

United States Severe Weather 1 2
by JLM- 63 replies
- 2.1k views
I got bored and started thinking, what if i create a thread specific to severe weather events? I thought about this partly because of the event that has occurred across portions of Texas and Oklahoma today, this activity is spreading over Arkansas as i type this. If you do not know, the Storm Prediction Center has 5 severe weather risk categories. Marginal (1/5) - 5% severe threat Slight (2/5) - 15% severe threat Enhanced (3/5) - 30% severe threat Moderate (4/5) - 45% severe threat High (5/5) - 60% severe threat So what do the percentages mean? Well, say you are under a Slight Risk, this means there is a 15% chance of seeing severe weather within a 25 …

The Florida thread inspired me to do one here based off of a happy medium between 1991-2020 averages, personal observation, (which made me do higher or lower in certain areas), and some educated guesses from trends in how the lines go from known areas to fill it in. Definitely in agreement with a narrow band of 9b above Florida and it probably terminates in extreme coastal Charleston County, SC. https://www.google.com/maps/d/edit?mid=1HHQbCcLVZkxooXPD1H4XC1oWRV8TPbA&fbclid=IwAR0_wNWuCvzHHCzeflSoTdT8MKzZpqR1PyCtRlO7T3KTqyDauBBuBiM5KlU&ll=31.325495808975415%2C-80.68797249999999&z=7

Coconut Palm - Strange Dead Rash Pattern?
by Hempress- 1 follower
- 3 replies
- 278 views
Hello! I have a problem with my coconut palm trees as they are developing a dead, lace-like rash (brown dead spots/blotches - not bugs) in a consistent pattern on the fronds. It started when the nights began getting colder in Silver Springs, Florida (Zone 9b) last week 10/20/22 (43 degrees). The only reason why I think it MIGHT be chill damage is because it began at this time. I don’t think it is a fungus because the spots are not watery, blurry or bleed to yellow/dead, but are more sharp, embedded and consistent in pattern. (see pics?). It doesn’t really look like a Manganese or Potassium deficiency and if they were sunburned wouldn't the end/tips and certain areas be m…

UK Winter 2022/23 & rainy season
by UK_Palms- 1 reply
- 355 views
I figure I better do a thread for this coming winter so that I am not clogging up the 'what is your current yard temperature' thread again. So far it has been incredibly mild and almost summer-like at times. The rain and unsettled windier conditions have arrived though as the Atlantic oceanic influence has reestablished, taking over from the high pressure, subtropical ridging associated with the Azores high and Csb conditions in southern England. No sign of any cold potential though yet, assuming we even get any this coming winter. ECMWF has temps pushing 26-27C / 80F on Halloween in London and southeast England. A far cry from the weather that we used to experience …

Every so often I'll wake up to this around the middle of the night. I check the radar, and it's always from about Cape Canaveral southward, isolated rain bands that bring the occasional downpour. Why does this only appear from Cape Canaveral and southward?

New thermometer recommendations
by RedRabbit- 8 replies
- 358 views
What do you guys suggest for a new thermometer? Here’s what I’m looking for: - Accurate - Has max/min readout - Ideally, connects to Wunderground or has some other data recording. - Don’t want to pay extra for an anemometer, I don’t have a decent place to install one and the HOA would probably throw a fit. Davis are great, but they’re overkill for my purposes. My last thermometer was a simple Acurite one that connected to Wunderground. It only cost something like $60, but it did the job. Unfortunately, they stopped selling this model. I know you guys are weather experts so I’m curious what you all would recommend.

My plant is fueling and I don’t know what to do with the new leaf, I have placed it near the heater that comes on a few hours in the night and by a window, I water once a week as well. Is that sufficient for the plant? mid the soil supposed to look whitish on top like a moss layer?
