the use of "es" in German

 I can certainly explain the use of "es" in German to refer to natural phenomena, in English.

The Impersonal "es" for Natural Phenomena in German

In German, the pronoun "es" (it) is frequently used as an impersonal subject when describing natural phenomena or general weather conditions. This is similar to how "it" is used in English in phrases like "It's raining." The key characteristic of "es" in these contexts is that it doesn't refer to a specific, tangible noun; rather, it functions as a placeholder subject for an action or state that has no clear agent.

Here's a detailed breakdown of its usage:

1. Weather and Atmospheric Conditions

This is perhaps the most common and straightforward use of "es" for natural phenomena. Verbs describing weather are almost always used with "es" as the impersonal subject.

• "Es regnet." (It's raining.)

• "Es schneit." (It's snowing.)

• "Es blitzt." (It's lightening.)

• "Es donnert." (It's thundering.)

• "Es hagelt." (It's hailing.)

• "Es friert." (It's freezing.)

• "Es taut." (It's thawing.)

• "Es ist windig." (It's windy.)

• "Es ist neblig." (It's foggy.)

• "Es ist sonnig." (It's sunny.)

  Note: While "es ist sonnig" uses "es," the core meaning here comes from the adjective "sonnig." You can also say "Die Sonne scheint" (The sun is shining) without "es."

Key Point: The verb is always conjugated in the 3rd person singular to agree with "es."

2. Temperature

When talking about temperature, "es" is also used as an impersonal subject, often with the verb "sein" (to be) or verbs like "werden" (to become).

• "Es ist warm." (It's warm.)
• "Es ist kalt." (It's cold.)
• "Es ist heiß." (It's hot.)
• "Es ist kühl." (It's cool.)
• "Wie viel Grad sind es?" (How many degrees is it?)
• "Es werden 20 Grad." (It will be 20 degrees.)

3. Time of Day / General Light Conditions

Although not strictly "natural phenomena" in the same way as weather, the concept of light and darkness related to the time of day often employs "es" impersonally.

• "Es wird dunkel." (It's getting dark.)
• "Es wird hell." (It's getting light.)
• "Es ist Tag." (It's daytime.)
• "Es ist Nacht." (It's nighttime.)

4. General Natural Occurrences (less common, but possible)

Sometimes, "es" can be used for less frequent, but still general natural occurrences.

• "Es riecht nach Frühling." (It smells like spring.) - Here, "es" points to a general atmospheric condition.
• "Es brennt im Wald." (There's a fire in the forest.) - While "fire" can be a concrete noun, "es brennt" can indicate a general burning activity without a specific agent, especially in a natural context.

Why "es"?

The use of "es" in these contexts reflects the German grammatical need for a subject in almost every sentence, even when there isn't a clear actor performing the verb. For natural phenomena, where the "actor" is the weather itself or an unidentifiable force, "es" fills this grammatical void. It's an "empty subject" or a "dummy subject" that allows the sentence to be grammatically complete.

Comparison with English "it"

The usage of "es" for natural phenomena in German is very similar to the impersonal "it" in English.

• German: "Es regnet." vs. English: "It is raining."
• German: "Es ist kalt." vs. English: "It is cold."

The main difference is that German is generally more strict about requiring a subject. If you were to omit "es" in these sentences, they would be grammatically incorrect in German, whereas in some very informal English contexts, you might hear "Raining!" or "Cold!" (though "It's raining" or "It's cold" are standard).

In summary, "es" for natural phenomena is a fundamental aspect of German grammar, serving as an impersonal subject to describe weather, temperature, and general atmospheric conditions when no specific agent is present.
