They often are the first sign of an approaching warm front or upper-level jet streak. Unlike cirrus, cirrostratus clouds form more of a widespread, veil-like layer similar to what stratus clouds do in low levels.
World Climate Zones Have you ever wondered why one area of the world is a desert, another a grassland, and another a rainforest? Why are there different forests and deserts, and why are there different types of life in each area?
The answer is climate. It is the long-term weather of that area at least 30 years. World biomes are controlled by climate. The climate of a region will determine what plants will grow there, and what animals will inhabit it.
All three components, climate, plants and animals are interwoven to create the fabric of a biome. Radiation that reaches the atmosphere here is at its most intense. In all other cases, the rays arrive at an angle to the surface and are less intense.
Cloud families and other cloud pictures/appearances In meteorology we divide clouds in 4 clouds families, which are in different heights of the troposphere: High level clouds (altitudes of km), medium level clouds ( km), low level clouds ( km) and clouds with large vertical extending (0 . The WMO International Cloud Atlas is the reference for the classification of clouds and meteorological meteors. It provides the definitions and descriptions of cloud types and meteors, and flow charts to help identify them. Cloud families and other cloud pictures/appearances. In meteorology we divide clouds in 4 clouds families, which are in different heights of the troposphere: High level clouds (altitudes of km), medium level clouds ( km), low level clouds ( km) and clouds with large vertical extending ( km).
The closer a place is to the poles, the smaller the angle and therefore the less intense the radiation. Our climate system is based on the location of these hot and cold air-mass regions and the atmospheric circulation created by trade winds and westerlies.
Trade winds north of the equator blow from the northeast.
South of the equator, they blow from the southeast. The trade winds of the two hemispheres meet near the equator, causing the air to rise. As the rising air cools, clouds and rain develop.
The resulting bands of cloudy and rainy weather near the equator create tropical conditions. Westerlies blow from the southwest on the Northern Hemisphere and from the northwest in the Southern Hemisphere. Westerlies steer storms from west to east across middle latitudes.
Air slowly descends to replace the air that blows away. Any moisture the air contains evaporates in the intense heat. The tropical deserts, such as the Sahara of Africa and the Sonoran of Mexico, exist under these regions.
Seasons The Earth rotates about its axis, which is tilted at Temperatures in these areas tend to be the hottest places on earth.
This creates the seasons. Each type is designated by a capital letter. A - Moist Tropical Climates are known for their high temperatures year round and for their large amount of year round rain.
B - Dry Climates are characterized by little rain and a huge daily temperature range. Two subgroups, S - semiarid or steppe, and W - arid or desert, are used with the B climates. These climates have warm,dry summers and cool, wet winters.
D - Continental Climates can be found in the interior regions of large land masses. Total precipitation is not very high and seasonal temperatures vary widely.
E - Cold Climates describe this climate type perfectly. These climates are part of areas where permanent ice and tundra are always present.Clouds are continually changing and appear in an infinite variety of forms.
This is a guide to the 10 main named groups of clouds. Clouds are continually changing and appear in an infinite variety of forms. The classification of clouds is based on a book written by Luke Howard, a London pharmacist and amateur meteorologist, in 1 AREA CLASSIFICATION IS NOT DIFFICULT (TO MAKE A MESS OF) Johannes Auret, Explolabs Consulting 1 Introduction Area classification (called classification of hazardous locations in our mines) is quite simply, the.
Hurricane Glossary - read about these tropical cyclones, how they form, how they are named, hurricane anatomy, the eye, eyewall, spiral rainbands, tracking storms, preparing for a storm, landfall, storm surges, and the end of the storm. The list of cloud types classifies the tropospheric genera as high (cirrus, cirrocumulus, cirrostratus), middle (altocumulus, altostratus), multi-level (nimbostratus, cumulus, cumulonimbus), and low (stratocumulus, stratus) according to the altitude level or levels at which each cloud is normally found.
Small cumulus are commonly grouped with the low clouds . NOAA National Weather Service Louisville, KY. US Dept of Commerce National Oceanic and Atmospheric Administration National Weather Service.
My own introduction to NLCs began many years ago when I accidentally encountered these eerie glowing clouds at the end of my Summer comet hunting sessions in the hours before dawn.
I recall feeling mesmerized by the beautiful structure and colours they contained and knew deep down that this phenomena was something very special.
