Lately we all have had enough of tragedy. The South Okanagan with its loss of Greg Norton and hockey with its loss of fifteen players and associates of the Humboldt Broncos.

I’m going to veer off into some self deprecating humor. As many of you know, I was born with a defect, a hormone deficiency which wasn’t discovered until I was in my early thirties. My medication treatment started with pills for four years, which gradually ceased their effectiveness, then shots for thirteen years, which created a lot of scar tissue in the injection site, then finally a cream to apply to my skin.

The cream was prescribed because it didn’t have to go through my liver like the shot serum had to. The cream was made up in the lab at the pharmacy. The pharmacist informed me that the skin didn’t absorb the cream easily so he would put a certain chemical in it for better absorbency. He went on to tell me that the chemical would cause my body to smell like garlic as the drug was being absorbed. I nodded in understanding and forgot about the matter.

Three years later I found myself working in an oil field truckers’ camp in Rainbow Lake, Alberta. My position was called Night Man, which meant that I worked from 6 pm to 6 am, and then slept all day. I kept an eye on the camp while the workers slept. I washed towels for the Camp Attendant, and I cleaned up the kitchen from the supper hour. I did that shift for fourteen days straight then went home for a week.

The medical plan of the trucking company had great coverage for my prescriptions. I switched my drug store manufactured cream to a commercially manufactured gel. The cream came in a big, clumsy, plastic jar while the gel came in individual sachets which were easier to administer.

I started the gel the day after finishing the cream. I walked into the kitchen at 4 pm to say hi to Shirley the cook. She looked at me and said, “You smell differently!” I thought for a moment, and said, “I’ve changed medications!” She said, “Oh, I thought you never bathed!” I replied, “Why didn’t you say something?” Her response, “I didn’t know how to word it.” She put up with that misunderstanding for three months, what a trooper!
I got an “aha” moment when I realized that it was the garlic smell from the cream medication that led her to assume I wasn’t bathing.

That reminds me of another time, many years ago, when I was a cook’s helper in Houston BC at a sawmill camp run by Northwood Pulp and Timber. One morning while I was preparing for lunch, the Millwright, who had worked all night, came in for his meal. I was cutting garlic close to the serving line when he asked me what I was doing. I told him and he asked for a garlic clove. Just for a joke I gave him the whole garlic corn and he took it. By the time I went back to get the corn from him he had eaten the whole thing! I was not amused but I took it in stride and went back to work.

When I got off shift at 5 pm and went into the bunkhouse, it absolutely reeked! Even my room stunk and I had the door closed and locked. The smell lingered for a week! Every pore in the Millwright exuded garlic stink, nauseateing us all. After three days the garlic had gone through the man but it took another four days to get the garlic air out the bunkhouse.

I’ve tried to avoid the overuse of garlic in my diet, but several times have failed to notice how much I’ve consumed. The smell always persisted much longer than I’d realized.
I think you would have to be nose blind to be a dentist or a doctor. I’m glad I’ve not been either considering the stink I’ve made others put up with.

Jet Stream

Cloud of the Day – Jet Stream

The jet stream was discovered by Japanese meteorologist Wasaburo Ooishi when making over 1200 balloon observations of high altitude winds between 1923 and 1925. This information was later used when the Japanese launched nearly 9000 hydrogen-filled paper balloons to carry explosives across the Pacific Ocean to North America during the second world war. The remnants of one of these were found near Lumby, British Columbia, Canada as late as 2014.

Jet streams — see video here — form at the tropopause, the boundary between the two lowest layers of the atmosphere, the troposphere and the stratosphere. There are four major jets, two in each of the northern and southern hemispheres. They are referred to as the polar and subtropical jets and they form at the boundaries of the atmosphere’s major circulating air masses. The northern hemisphere’s polar jet flows at the mid- to northern latitudes and is a regular feature of television weather reports for many of us. The southern hemisphere’s polar jet mostly just circles Antarctica. The subtropical jets are weaker than the polar jets and don’t have as much effect on our weather patterns. There are other jet streams that form at particular times of the year or in particular places, but they don’t have much wider effect either.

Jet streams form at the boundaries of air masses where there are steep pressure and temperature gradients. The tendency of the air to move rapidly from high to low pressure down this steep pressure gradient, and its diversion by the Coriolis force results in a strong current of air at the boundary between the air masses. This current flows generally from west to east in prevailing westerlies. Since weather systems also tend to form at the interface between air masses, it is common for those systems to follow the jet stream. The polar jet streams track north and south with the seasons in concert with the Sun. The streams are quite concentrated phenomena, being only a few hundred kilometers wide and less than five thick.

The wind speed in a jet is often a hundred kilometers per hour and can exceed four hundred. It is easy to see how this could affect the flight of aircraft by reducing or prolonging flight time, depending on whether the flight was with or against the flow. Before this was understood, aircraft were known to take longer than anticipated to reach their destination, sometimes running out of fuel before arriving.

The jet stream is not straight, but rather meanders in its flow from west to east. These meanders look like waves and are called Rossby waves. These waves also travel from west to east, carrying the different weather on their north and south sides across the land below. Recently, probably due to climate change, Rossby waves have been stalling their eastward movement for unusually long periods, subjecting areas to prolonged rainfall or heatwaves. These extreme weather conditions are becoming more common.

In a future post we will cover related phenomena such as the Southern Oscillation, el niño/la niña, the polar vortex and the Dust Bowl.

Just a quick mention about the GMO issue. The discussion is not likely to go away any time soon.

I came across an interesting web site which had a debate on GMO’s. During the debate I came to the understanding that the foundation of GMO’s argument is based on feeding the world and reducing pesticide and herbicide use. Who can argue with that? One hundred thirty countries have signed on to use GMO grown food. In the coming years we will know its impact, negative, positive or no change.

Combating the Elements

The coming spring is the time when tree fruit blossoms of soft fruits are most at risk from frost. On Wally’s farm, he planted the peaches on the highest part of the farm which was the ridge. He then planted pears on the west side of the ridge and cherries on the east side.

The term commonly known as “smudge pots” was frowned upon by Wally. He said the correct usage was “fire pots” because it was the heat from the fire which protected the fragile blossoms from the frosty air and not the smudgy smoke.

Wally would place the fire pots in all three soft fruit blocks. The pots were metal containers each capable of holding two gallons ( 8 litres ) of diesel fuel. If I remember right, the pots were about 30 feet apart and placed to the side of the tractor track for easy refilling.

Wally and Auntie Kay carefully listened to the evening radio frost report. If there was a chance of frost they slept little for they checked their thermometer regularly.

When the thermometer dipped below the safe point, Wally would take the blow torch out and light all the fire pots. That was quite a task I must say!

When the frost threat was over, the flame was extinguished by placing a wooden shingle over top of each pot snuffing it out. On occasion, the pots were lighted earlier in the evening than expected. It was those nights when the pots burned all the fuel and had to be replenished before the night was over.

In the morning as the sun rose, the Valley air was laced with diesel smoke from another gallant fight with the killing frost. The work wasn’t finished though, for the pots all needed to be refilled before the grower and his wife sought the comfort of their bed to get a few winks before joining the ranks of the day workers.
