The Other Side of the Mountain: Rainshadows
Mountain ranges have a major impact on moist air moving over them. On the windward side, upsloping air leads to a region of heavy precipitation near the summits. But in the descent on the ridge lee, descending air and decreased precipitation forms what we term the rainshadow.

A Study in Opposites: Thundersnow
For most North Americans, the combination, known as 'thundersnow', is a very unusual event. Even where they are most common, thundersnow occurs no more than a few times per year, usually when winter storms with substantial warm and humid air sectors spawn thunderstorms along their fronts, or when air crosses a large lake or rises over a mountain range.

Arctic Outbreaks
Arctic Outbreaks. They happen in all months of the year and can rate headlines during spring, summer, or early autumn if they bring extreme drops in temperature or killing frost. But it is during the winter that they receive the most attention because arctic outbreaks can drop air temperatures to hazardous levels, increase demands for home heating fuels, produce lake/sea effect snows, or in their deepest southern penetration kill sensitive fruit and vegetable crops in the southern American states.

Blizzard!
While the media rush to call any severe or heavy snowstorm a blizzard, true blizzards have a strict definition according to meteorologists, and snow need not even fall in a blizzard. Blizzards take on different characteristics when they rage around North America, combining wind and temperature and snow into a variety of recipes, though they all start as low pressure systems.

Cloudbursts
Have you ever gone out for a long walk, run, or bike ride on a gorgeous summer day and been caught in a torrential cloudburst? Bad enough to be caught in the rain, but cloudbursts can leave you drenched to the bone. But have you ever watched the approach of a thunderstorm darken the sky and then been surprised at how bright the day became during the heaviest downpour?

Cumulus Humilis: A Fair Weather Cloudscape
The dawn brought clear sky But, in a few hours, the warm sun would break the morning chill, and by mid-morning the perfectly clear sky would begin to lose its fair complexion as small buds of whiteness pop up hither and yon. So started a day when cumulus humilis, the most basic of the cumulus cloud family, would fill the skyscape. This cloud type often is the forerunner to larger, more developed cumulus varieties that fill the afternoon sky. But today, these fair-weather cumuli dot the sky within the large high-pressure cell that sat over the region.

Diamond Dust: Snow Without Clouds
During the depths of winter cold, we often hear some weather sage observe, "It's too cold to snow." Truth is, it is never too cold to snow. At very cold temperatures, 40 below zero (C or F) and colder, snow can actually fall out of the clear blue sky without intervening clouds, a weather condition known appropriately enough as diamond dust.

Dry Thunderstorms
When you hear the word thunderstorm in the daily weather forecast, you automatically think of thunder and lightning accompanied by rain, often as a drenching cloudburst, and wind, gusty at times. Not all thunderstorms are wet, however, and that worries those watching for or fighting wildfires. These thunderstorms are called dry thunderstorms.

Frost on the Pumpkin
Short days and low sun angles enhance the dreariness of November skies frequently flushed with stratus clouds from dusk to dawn. But at times, November mornings dawn with a quiet, spectacularly brilliant beauty. These are the mornings touched by the brush of Jack Frost.

Frost Pockets
The lengthening nights during the late summer and autumn bring noticeably colder minimum temperatures across most of North America. If such nights have clear skies and fairly calm regional winds, the potential for temperatures to fall below the freezing mark increases as the days move on toward winter. This is especially true in low-lying terrain, hollows and drainage bottoms where cold air can pool. Such areas are more susceptible to frost than the surrounding terrain and are therefore known as frost pockets.

Gap Winds
Terrain interacts with the atmosphere in many ways to alter the weather. If winds push through the terrain in spots, rather than going over it, another set of wind phenomena arises, the gap winds. Gap winds are high-speed winds associated with gaps or low elevation areas in mountainous terrain, and whose direction more or less parallels the gap axis.

Gulf of Alaska Storms
Storms move out of the Gulf of Alaska into the Pacific Northwest with great regularity, as many as three or four per week during the height of the winter storm season. Winter Gulf of Alaska storms typically sport winds in excess of 80 km/h (50 mph) with corresponding high waves. Some storms rival the strength of the great hurricanes/typhoons and would be considered as such if their origins were tropical rather than polar.

Nor'easters and Alberta Clippers
The great tropical storms roaming the world's oceans and seas have earned the right for individual names. Extratropical cyclonic storms, those forming from the clash of polar and tropical air masses, have not yet been honoured with individual names. However, some extratropical storms take on such unique characteristics that they are often recognized with a unique name for the genre: the Nor'easter along the Atlantic coast, the Alberta Clipper that races across the continent our of the Alberta plains.

The Glory and the Brockenspectre
Glories appear as a full circle, their coloured rings centered on the observer's shadow. Prior to the advent of regular high-altitude flight, the glory appeared only to those who ascended to high mountain elevations. Today, we can see glories regularly from aircraft flying in the sunlight above uniform cloud decks. A glory is only visible when sunlight is at the observer's back; therefore, they are always exactly opposite the sun.

Turning Lakes
We generally think of weather processes as occurring from the surface upward into the atmosphere, but weather has its influences downward into the soil and water bodies as well. Seasonal weather interactions play major roles in the processes and ecology of even the smallest freshwater lakes. One of the more important is the semi-annual turnover of a lake's water mass.

Winds of the City
Walk around any city where buildings rise more than a few stories, and you will experience areas with stronger and gustier winds than felt outside the urban area, at airports, or on sports fields. The prime cause of such urban winds is the redirecting of the over-ridding wind field by the structures themselves.

A Record Setting Day
For those who love weather in all its varied forms, extreme or rare weather events often hold great allure. Spawned by our love of statistics, one extreme event that catches our attention is the breaking of daily temperature records. Whether a record hot day or record cold day, it is sure make local news headlines. If today's weather set a record for either maximum or minimum temperature, you would likely respond with a modicum of interest. If I told you that this day broke both the daily maximum and minimum temperature record, you might exhibit degree of incredulity. I call such days: double record days.

Neither Rain Nor Snow
Neither rain nor snow, nor freezing rain, for that matter. That is how one must often characterize winter precipitation. Rain and snow are just the most common members of the winter precipitation congregation, but not the only ones. Others include: ice pellets, snow grains, graupel, ice crystals and ice needles and also known by local names in different regions such as sleet, hail, soft hail, snow pellets and diamond dust.

Why Are Lightning Bolts Not Straight?
If you've ever watched a spark of static electricity jump from an object like a doorknob to your finger, you perhaps noted that mini-bolt followed a fairly straight-line path from the object to your finger. Lightning bolts are essentially the granddaddy version of that static spark, so why do lightning bolts generally appear so jagged and forked? The answer for lightning's jaggedness arises in its size and formation process.
