It is probably because of the expansion of the gas (fumes) in the fuel tank. Many vehicles and especially motorcycles (because the fuel tank is exposed to the sun) do this, sometimes it even makes a hissing sound as the gas escapes, sometimes it makes a whining/humming sound
Violent changes in weather are called fronts. These fronts can refer to violent temperature changes such as a cold or hot front for example.
Cold. Picture winters like living in a big freezer that's loaded up with ice packs if you go outside in the winter. In the summer though it gets around 80 everyday from April to September

The severe weather decreases the population because it can destroy houses and much more damaging things. Whenever people hear about storms like these, people want to leave to be safe.
According to the Farmer's Almanac October should be cooler and drier than usual.
The question is nowehere near specific enough to answer.
When an engine is cold, the oil is thicker, and flows slower. When oil doesn't get to valvetrain components quickly, you'll hear knocking, also known as valvetrain clatter. As the engine warms up the knocking should go away.
Rain, blizzard, thunderstorm, tornado, hurricane, very cold temperature.
Is it a lifter ticking?
Hear the spluttering sound when water is sprinkled on hot oil.
Often on a weather report you hear a local weather forecast. As well as hearing a national forecast. They also announce any watches or warnings threats from the area.
You never hear the fuel injectors. You may hear the fuel pump if you listen carefully. Start by replacing the fuel filter. If that does not help, have a fuel pressure test run to see if the pump is weak.
That is very likely a slightly loose serpentine or other drive belt. In colder weather belts get stiffer and slicker, fluid (as in the steering pump) gets thicker and harder to turn . If it diminishes when your car warms up, that is almost certainly the cause. - Let a mechanic hear it and diagnose it.

Violent changes in weather are called fronts. These fronts can refer to violent temperature changes such as a cold or hot front for example.
I would start by replacing the oil pressure sending unit. If that does not correct the problem, I would look closely at the gage itself. If you hear any valve train noise at cold startup, you need to have an oil pressure test run to make sure you actually have good oil pressure when starting the engine cold. Possibly the gage is correct and you do have 0 oil pressure when cold.
