"frost bucket" frost pocket or frost hollow effect on predicted wind speed

(1/1)

bovine421:
I realize something with this last frost event. When looking at predicted wind speeds hourly it doesn't quite match my weather station. My weather station is not above my roof. When the winds come from the North and the West because of large oak trees and adjacent buildings the wind speeds are not as predicted. Especially when the winds get down in the lite range. During the last event  weather app predicted wind speeds for 7 to 8 miles an hour I didn't get much comfort because my weather station showed winds at 2 to 3 mph. So the dilemma can be 6-1 way half a dozen another. Frost if the winds are high enough I won't have to use irrigation.  If the winds are too high I can't use irrigation. So it's kind of a scenario of predicting the predicted wind speed. It was mentioned on this form in the past there's definitely a frost trough over in Lakeland by the airport. I'm surprising that elevation and Landscaping features can cause these pockets troughs Hollows.

Key Characteristics of a Frost Bucket
Cold Air Pooling: Because cold air is denser than warm air, it flows downhill (katabatic flow) and settles in these low-lying,, often stagnant spots.
Topographical Barriers: Barriers such as embankments, walls, or thick hedges can block the downhill drainage of cold air, forcing it to trap behind them and create a "bucket" effect.
Temperature Inversion: In these areas, the coldest air is at the bottom (ground level), while warmer air sits above it.
Extended Season: Frost pockets often experience earlier autumn frosts and later spring frosts, reducing the growing season for plants.
Visual Indicators: Early morning fog or mist that lingers in a specific, low-lying spot while surrounding areas are clear often indicates a frost pocket.

Best I can tell about predicted wind speeds for Sunday p.m. and Monday a.m. might not have Frost but then again predicting the predicted

I've watched frost pockets for years and know where many of them are around my yard and my Dad's property. I had never thought about fog being an indicator, though. That is a handy tip when looking at a new property or predicting frost pockets.

On a related note, a good friend used to work in a grove related business. He mentioned that one of the groves he visited frequently had a lot of topography and frequently had freeze damage on the trees down hill by the swamp. One year they had a particularly cold snap, though, and that was the only part of the grave that survived. 🤔 Sometimes strange things happen. I wonder if those trees had gone dormant from the consistently greater cold and were not as harmed as a result.

Artocarpus:
Galatians, maybe it was an advective freeze event and the wind modified the air passing over swampy ground warmed the trees nearby too.

I think that is exactly what happened.
