Nasik Climate History The Heat Index is a measure of how hot it feels when relative humidity is added to actual air temperature. From this a comfort level is calculated providing categories on how heat conditions might adversely affect someone.Comfort Levels: Given average maximum temperatures and humidity levels you can expect dangerous heat conditions. Sunstroke, muscle cramps and heat exhaustion are likely.rom this a comfort level is calculated providing categories on how heat conditions might adversely affect someone.

- Index score: (100 = National Average) for an area is compared to the national average of 100. A score of 200 indicates twice the national average, while 50 indicates half the national average. Note: A higher Weather Index score represents better overall weather (higher number good). A higher Hail, Hurricane or Tornado Index means the chance of that weather event is higher (higher number bad). Information is deemed reliable but not guaranteed.

The UV Index About the UV Index. The UV Index is a forecast of the probable intensity of skin damaging ultraviolet radiation reaching the surface during the solar noon hour: 11:30-12:30 Local Standard Time, or 12:30-13:30 Local Daylight Time. The greater the UV Index is the greater the amount of skin damaging UV radiation.

Air quality index Air quality index. An air quality index (AQI) is a number used by government agencies to communicate to the public how polluted the air currently is or how polluted it is forecast to become. As the AQI increases, an increasingly large percentage of the population is likely to experience increasingly severe adverse health effects.

How To Construct an Index for Research By Ashley Crossman. An index is composite measure of variables, or a way of measuring a construct using more than one data item. An index is an accumulation of scores from a variety of individual items. There are four main steps involved in creating an index: selecting possible items, examining their empirical relationships, scoring the index, and validating it.

- National Weather Service. The Heat Index is a measure of how hot it really feels when relative humidity is factored in with the actual air temperature. To find the Heat Index temperature, look at the Heat Index Chart above or check our Heat Index Calculator. As an example, if the air temperature is 96°F and the relative humidity is 65%, the heat index--how hot it feels--is 121°F. The red area without numbers indicates extreme danger.

- Stock market index. A stock index or stock market index is a measurement of the value of a section of the stock market. It is computed from the prices of selected stocks (typically a weighted average). It is a tool used by investors and financial managers to describe the market, and to compare the return on specific investments.

What is the heat index? That's a partly valid phrase you may have heard in the summer, but it's actually both. The heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature. This has important considerations for the human body's comfort.When the body gets too hot, it begins to perspire or sweat to cool itself off.he body actually feels cooler in arid conditions. There is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decrease).

Historical: What is the Air Quality Index? The calculated number for each pollutant is referred to as a sub-index. At a given site, the highest sub-index for any given hour becomes the AQI reading for that hour. The index is a relative scale, in that, the lower the index, the better the air quality. If the AQI reading is below 16, the air quality is in the very good category.

What is the heat index? For example, if the air temperature is 100°F and the relative humidity is 55%, the heat index will be 124°F. When the relative humidity is low, the apparent temperature can actually be lower than the air temperature. For example, if the air temperature is 100°F and the relative humidity is 15%, the heat index is 96°F (use this calculator). In the Panhandles, we commonly see hot temperatures during the summer, but the low relative humidity values make it somewhat unusual to see dangerous heat index values (i.e. 103°F or greater).

Heat Index Heat Index. Temperature vs. Humidity. How to read the chart: find the temperature on the left hand side, then move to the right until you find the column for the approximate relative humidity. That number will be the temperature that it will feel like. Example: A temperature of 95 and relative humidity of 50% will feel like 107 degrees.

Database index An index is a copy of select columns of data from a table that can be searched very efficiently that also includes a low-level disk block address or direct link to the complete row of data it was copied from.Some databases extend the power of indexing by letting developers create indices on functions or expressions.ndexes are used to quickly locate data without having to search every row in a database table every time a database table is accessed. Indexes can be created using one or more columns of a database table, providing the basis for both rapid random lookups and efficient access of ordered records.

Color index In astronomy, the color index is a simple numerical expression that determines the color of an object, which in the case of a star gives its temperature. The smaller the color index, the more blue (or hotter) the object is. Conversely, the larger the color index, the more red (or cooler) the object is. This is a consequence of the logarithmic magnitude scale, in which brighter objects have smaller (more negative) magnitudes than dimmer ones.
